This really bothers me every time I work with a cell array of strings. Isn't there a more elegant way to iterate over the cell array of strings to directly getting the ...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 ...Replace a missing string in a table.

Answers (1) 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: If you need to eliminate characters that occur 3 or more times throughout the whole string, I ...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 ...

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.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 times in dim2.

str = append(str1, ' ' ,str2) str =. "Good Morning". As an alternative, you can use the plus operator to combine strings. str = str1 + ' ' + str2. str =. "Good Morning". However, the best practice is to use append when you do not know whether the input arguments are strings, character vectors, or cell arrays of character vectors.

I'm not your teacher and you will not get any grades from me. But if you ask me for a good solution, I will suggest another method due to my experiences with Matlab and other programming languages. I have no problem, if you have another opinion. Feel free to post answers with your preferred method. Remember that I am a Matlab user as you are.

So that the matrix M look like: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: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.'on' contains two characters. Repeating it for N rows would give an Nx2 matrix, not a column vector. Posibly you mean a column vector of strings, like in,

C = union(A,B, ___,'rows') and C = union(A,B,'rows', ___) treat each row of A and each row of B as single entities and return the combined rows from A and B, with no repetitions.You must specify A and B and optionally can specify setOrder.

The sprintf function returns only a string scalar or a character vector. If A has multiple rows, then compose returns str as a string array or cell array with the same number of rows. compose repeats formatSpec in each row of str , with formatted values from the corresponding row of A . 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 =. "". Create an empty character vector using single quotes.

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 ...

An empty string contains zero characters. When you display an empty string, the result is a pair of double quotes with nothing between them (""). The missing string is the string equivalent to NaN for numeric arrays. It indicates where a string array has missing values. When you display a missing string, the result is <missing>, with no ...
