How do you make a cell array of character vectors?
To create a cell array of character vectors, use curly braces, {} , just as you would to create any cell array. For example, use a cell array of character vectors to store a list of names. The character vectors in C can have different lengths because a cell array does not require that its contents have the same size.
How do you make a cell array of character vectors in Matlab?
Description. C = cellstr( A ) converts A to a cell array of character vectors. For instance, if A is a string, “foo” , C is a cell array containing a character vector, {‘foo’} . C = cellstr( A , dateFmt ) , where A is a datetime or duration array, applies the specified format, such as “HH:mm:ss” .

- JavaCharArray[1] = ‘b’;
- JavaCharArray[2] = ‘c’;
- JavaCharArray[3] = ‘d’;
- JavaCharArray[4] = ‘e’;
What is the difference between str2num and str2double?
MATLAB – str2num() vs str2double()
The problems with str2num() are that it doesn’t support cell arrays, and that because it uses an eval() function, wierd things can happen if your string includes a function call. str2double() is supposedly faster as well.
