Output data type of text, specified as the comma-separated pair consisting of 'TextType' and either 'char' or 'string'. If you specify the value 'char', then textscan returns text as a cell array of character vectors. If you specify the value 'string', then textscan returns text as an array of type string.You can concatenate strings using strcat. If you plan on concatenating numbers as strings, you must first use num2str to convert the numbers to strings. Also, strings can't be stored in a vector or matrix, so f must be defined as a cell array, and must be indexed using {and } (instead of normal round brackets).Say I have a column vector x=[a;b;c]. I want to repeat each element n times to make a long length(x)*n vector. For example, for n=3, the answer would be: ans= a a a b b b ...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).
