Matlab repeat string

MATLAB parses each input character vector or string from left to right, attempting to match the text in the character vector or string with the first element of the regular expression. During this process, MATLAB skips over any text that does not match.

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.Selected part of the text, returned as a string array, a character vector, or a cell array of character vectors. token includes all text starting at the first character that is not a delimiter and ending at, but not including, the next delimiter. str and token are the same data type. Data Types: string | char | cell.Hi, how do I delete duplicate values from an array or a vector provided that unique function is not used and that the place of the value does not remain empty or zero. The result is like this The result is like thisstr, 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 .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.Create a Matrix with multiple repeated strings.
