Matlab repeat string.

The old string and new string inputs can be single strings or tall arrays of strings with the same size. For more information, see Tall Arrays for Out-of-Memory Data . C/C++ Code Generation Generate C and C++ code using MATLAB® Coder™.In MATLAB square brackets are a concatenation operator (not a "list" operator, which MATLAB does not have, the closest thing is perhaps a cell array), so your example is exactly equivalent to this: v = 'dogdogdogdog'Open in MATLAB Online. Hi Ebtesam, If you want to delete any character which is repeated three or more times in a row, you can substitute the @unique function in your cellfun () with a regexp that searches for 3+ character matches and replaces them with nothing: Theme. Copy. f = @ (s) regexprep (s, ' (\S)\1\1+', ''); cellfun (f,Input ...Removing duplicate strings from an array and... Learn more about unique, duplicate, repeating, strings so i'm having trouble trying to eliminate repetitions from my arrays. i've been using unique but can't have the first instance of the element in the return.Each element of a character array stores only one character, so (until the string class was introduced) the only way to store multiple characters using a scalar index (as the question poses) is to use a cell array. From that persepctive it is not a "workaround", it is the correct solution for versions of MATLAB before R2016b.

end executes a group of statements in a loop for a specified number of times. values has one of the following forms: initVal:endVal — Increment the index variable from initVal to endVal by 1, and repeat execution of statements until index is greater than endVal. initVal:step:endVal — Increment index by the value step on each iteration, or ...Basic Syntax: output = repelem(v, n) Where: v: The input vector or scalar to be repeated. n: The number of times each element of v should be repeated. Returns a …

To programmatically exit the loop, use a break statement. To skip the rest of the instructions in the loop and begin the next iteration, use a continue statement.. Avoid assigning a value to the index variable within the loop statements. The for statement overrides any changes made to index within the loop.. To iterate over the values of a single column vector, first transpose it to create a ...1 Answer. Sorted by: 2. Assuming you have the following variables: test1=repmat({'aaaa'},1,3); test2 = 'cccc'; test3=repmat({'bbbb'},1,3); then test1 and test3 …

Copy Command. Create a 4-by-1 string array by reading each line from a text file as a separate string. lines = readlines( "badpoem.txt") lines = 4x1 string. "Oranges and lemons," "Pineapples and tea." "Orangutans and monkeys," "Dragonflys or fleas." The simplest way to repeat a string in Python is with the * operator. Use the operator on a string to repeat the string a provided number of times. The syntax for the operation is: result = string * number. The code below demonstrates how to repeat the string " Hello, world! " five times: result = "Hello, world!" * 5.How to remove repeating characters in a... Learn more about arrays, char MATLABnewStr = split(str) divides str at whitespace characters and returns the result as the output array newStr.The input array str can be a string array, character vector, or cell array of character vectors. If str is a string array, then so is newStr.Otherwise, newStr is a cell array of character vectors.newStr does not include the whitespace characters from str.

example. tf = strcmp(s1,s2) compares s1 and s2 and returns 1 ( true) if the two are identical and 0 ( false ) otherwise. Text is considered identical if the size and content of each are the same. The return result tf is of data type logical. The input arguments can be any combination of string arrays, character vectors, and cell arrays of ...

str, old, and new must be a string scalar, a character vector, or a cell array containing not more than one character vector. Thread-Based Environment Run code in the background using MATLAB® backgroundPool or accelerate code with Parallel Computing Toolbox™ ThreadPool .

Description. u = repelem(v,n) , where v is a scalar or vector, returns a vector of repeated elements of v. If n is a scalar, then each element of v is repeated n times. The length of u is length(v)*n. If n is a vector, then it must be the same length as v. Each element of n specifies the number of times to repeat the corresponding element of v.I understood from your question that the desired result '12345' was a string, not a number (otherwise use Shai's answer less the num2str part). So you want to assign a string to the first element of a variable c?If c has to store other strings of possibly different lengths, c should be a cell array; and you'd just do c{1} = b - Luis Mendo Character arrays and string arrays provide storage for text data in MATLAB ®. A character array is a sequence of characters, just as a numeric array is a sequence of numbers. A typical use is to store short pieces of text as character vectors, such as c = 'Hello. World'. A string array is a container for pieces of text. Hello there, if I have a cell array as following: in which the first column is constructed of type 'char' for each element, how can I extract this first col. without duplicates?

Count the number of occurrences of the string, red, in string arrays. You can create a string using double quotes. str = "paired with red shoes". str =. "paired with red shoes". To count the occurrences of red, use the count function. In this example, the result is 2 because red is also part of the word paired.To build block arrays by forming the tensor product of the input with an array of ones, use kron.For example, to stack the row vector A = 1:3 four times vertically, you can use B = kron(A,ones(4,1)).Based on Abhinav's answer and some tests, I wrote a function which is ALWAYS faster than repmat ()! It uses the same parameters, except for the first parameter which must be a vector and not a matrix. function vec = repvec( vec, rows, cols ) %REPVEC Replicates a vector. % Replicates a vector rows times in dim1 and cols …Y = circshift(A,K) circularly shifts the elements in array A by K positions. If K is an integer, then circshift shifts along the first dimension of A whose size does not equal 1. If K is a vector of integers, then each element of K indicates the shift amount in the corresponding dimension of A. Note. The default behavior of circshift(A,K) where ...the command (hist) counts the frequency (number of repetitions) of a certain value in a vector. if you use: hist(a), matlab will divide the whole range of values to 10 periods, and count the repetitions of values lying within these ranges. however, if you use: hist(a,b), then the repetitions are counted against the reference (b). so when you count …a = randi([1 5],200,1); Find the unique elements in the vector. Return the index vectors ia and ic. [C,ia,ic] = unique(a); Count the number of times each element in C appears in a. Specify ic as the first input to accumarray and 1 as the second input so that the function counts repeated subscripts in ic.

Toshi is back for today's guest post. You may have seen Toshi's earlier posts about text analytics and he often deals with text in his data analysis. So he is very excited about new string arrays in R2016b.. One of the new features I love in R2016b is string arrays, which give you a new way to handle text in MATLAB in addition to the familiar character arrays and cell arrays of character vectors.

Description. u = repelem(v,n) , where v is a scalar or vector, returns a vector of repeated elements of v. If n is a scalar, then each element of v is repeated n times. The length of u is length(v)*n. If n is a vector, then it must be the same length as v. Each element of n specifies the number of times to repeat the corresponding element of v.To use string array, make sure you have MATLAB 2016b+ where you can use double quotation mark: names = ["Tom", "Dick", "Harry"] Otherwise, use cell array: names = {'Tom', 'Dick', 'Harry'} And access the elements using curly bracket and index: names{1} % Tom. names{2} % Dick. There are also a number of other mistakes in your code:To answer your question you can create a cell array with the same string n-times with deal. Theme. Copy. doc deal. Specifically you can make a 1x5 cell array filename have the value saved in name with: Theme. Copy. [filename {1:5}] = deal (name); you may want to consider a structure array ...C = vertcat(A,B) concatenates B vertically to the end of A when A and B have compatible sizes (the lengths of the dimensions match except in the first dimension). example. C = vertcat(A1,A2,…,An) concatenates A1, A2, … , An vertically. vertcat is equivalent to using square brackets to vertically concatenate or append arrays.To answer your question you can create a cell array with the same string n-times with deal. doc deal Specifically you can make a 1x5 cell array filename have the …newStr = split(str) divides str at whitespace characters and returns the result as the output array newStr.The input array str can be a string array, character vector, or cell array of character vectors. If str is a string array, then so is newStr.Otherwise, newStr is a cell array of character vectors.newStr does not include the whitespace characters from str.You can test a string array for empty strings using the == operator. You can create an empty string using double quotes with nothing between them ( "" ). Note that the size of str is 1-by-1, not 0-by-0. However, str contains zero characters. str = "". str =. "".
