Matlab repeat string
Add Numbers to Strings. The simplest way to combine text and numbers is to use the plus operator (+). This operator automatically converts numeric values to strings when the other operands are strings. For example, plot a sine wave. Calculate the frequency of the wave and add a string representing that value in the title of the plot.It provides a flexible way to create repeated patterns within an array, allowing for efficient handling of repetitive tasks in data processing and analysis. The repelem() function in MATLAB has two primary syntaxes: 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 ...This MATLAB function returns the starting index of each substring of str that matches the character patterns specified by the regular expression. ... , then so is the output. If str is a string array, then the output is a cell array in which the innermost cells contain string arrays. When you specify the 'once' option to return only one match, ...

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.If you want to create a 4 element string array you don't need to use a loop. Adding a string scalar and a numeric vector converts the numeric vector to a string array of the same size then adds on that string scalar to each element. You can even use implicit expansion.From the documentation for repelem: repelem Replicate elements of an array. U = repelem (V,N), where V is a vector, returns a vector of repeated elements of V. So what you want is: >> repelem([1 2 3 4],4) answered Sep 16, 2017 at 22:13. Martin Dinov. 8,787 3 29 41.Categorical Arrays. categorical is a data type to store data with values from a finite set of discrete categories. For example, the syntax C. = categorical({'R','G','B','B','G','B'}) creates a categorical array with six elements that belong to the categories R , G, or B. A categorical array provides efficient storage and convenient manipulation ...Repeat cells in a cell array - Matlab [duplicate] Ask Question Asked 9 years, 9 months ago. Modified 9 years, 9 months ago. ... Convert cell array of cells into cell array of strings in MATLAB. 3. Apply function to every pair of cells in a cell array. 325. Remove duplicates by columns A, keeping the row with the highest value in column B ...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)).Looping through an array of strings. Learn more about loop, string array Hello, I have an array of trial names (i.e. trials = {'Standing', 'Walking'}, etc.) and I want to loop through the array to create new variables like so: for trialnum = 1:11; trial = trials(t...It would be better to have your 2D pages in the first two dimensions. I.e., B(:,:,j) instead of B(j,:,:). That way the 2D slices are contiguous in memory, and there are many functions in MATLAB and the FEX file exchange that naturally work with "stacked" 3D arrays where the 2D slice is the first two dimensions. E.g., pagemtimes( ).test3=repmat({'bbbb'},1,3); then test1 and test3 will be 1x3 cell arrays, while test2 is simply a string or char array. If you would now use. final = {test1, test2, test3}; then final would become a 1x3 cell, where the first element is again a 1x3 cell ( test1 ), the second element is a string ( test2) and the third element is again a 1x3 cell.Accepted Answer. Your code has multiple bugs, in particular wrong indexing into the cell array, missing format specifier in the |sprintf| format string, and you are overwriting half of your data on each iteration. Try this instead: col = cell (2,num); % preallocate. col {1,k} = sprintf ('X_%d',k); % I fixed your format string. col {2,k ...If you only have text strsplit does exactly what you want and I feel that is a bit simpler to use. Theme. Copy. strsplit ('ab cd ef') ans =. 1×3 cell array. 'ab' 'cd' 'ef'. You can specify the delimiter if it is not spaces that are your delimiters. If you however want to split a string into single characters you could use cellstr.Your problems are probably caused by the way MATLAB handles strings. MATLAB strings are just arrays of characters. When you call ['cow','dog','cat'], you are forming 'cowdogcat' because [] concatenates arrays without any nesting. If you want nesting behaviour you can use cell arrays which are built using {}.C = textscan(chr,formatSpec) reads the text from character vector chr into cell array C.When reading text from a character vector, repeated calls to textscan restart the scan from the beginning each time. To restart a scan from the last position, request a position output.. textscan attempts to match the data in character vector chr to the format specified in formatSpec.Create a Matrix with multiple repeated strings.

In MATLAB square brackets are a concatenation operator (not a "list" operator, which MATLAB does not have, the closest thing is perhaps a cell ...When we enter the loop, total is zero - the value assigned to it beforehand. The first time through, the loop body adds the value of the first even number (2) to the old value of total (0), and updates total to refer to that new value. On the next loop iteration, even_number is 4 and the initial value of total is 2, so the new value assigned to ...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 ...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)).. To create block arrays and perform a binary operation in a single pass, use bsxfun.In some cases, bsxfun provides a simpler and more memory efficient solution.newStr = strip(str,side) removes all consecutive whitespace characters from the side specified by side. The side argument can be 'left', 'right', or 'both'. newStr = strip( ___,stripCharacter) strips the character specified by stripCharacter, instead of whitespace characters. You can use any of the input arguments in the previous syntaxes.To enable your existing code to accept string arrays as input, add a call to convertStringsToChars at the beginning of your code. For example, if you have defined a function myFunc that accepts three input arguments, process all three inputs using convertStringsToChars .Replace a missing string in a table. Learn more about table, missing values, strings I want to replace all missing strings in a table with a string of my choice, say 'unknown'.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))..

Splitting changes names from a 5-by-1 string array to a 5-by-2 array. For a string array or cell array of any size, split orieAccepted Answer: Sean de Wolski. Hello, I am tryingCombine the strings in str along the first dimension. By defaul 1. If the n vectors have the same size ( 1,m in your case, i.e. they are all row-vectors) you can concatenate them in a single matrix where each row is a vector. This concatenation can be easily done as following: R_total=[R1;R2;...;Rn]; and then process one-by-one the rows of R_total (i.e. single vectors) in a for-loop: Basic Syntax: output = repelem(v, n) Where: v: The input vecto Greetings, I am looking for a simple way to create a legend that defines a key for every loop iteration of a variable that is used as a for loop instrumentation.

MATLAB provides a rich set of fun 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.
