How can i create empty 20x72 string.

I need empty string to fill the next any process.

These following function is not help to me:

zeros(20,72)

char(' ' *ones(20,72)) ---> I am working with Binary "1" and "0" numbers. This function is not giving to me the true values.

Your existing char(' ' *ones(20,72)) gives you a 20 x 72 char array of blanks, and is what you probably need. But what you might be looking for instead is

repmat({''}, 20, 72)

This will be a 20 x 72 cell array, each entry of which is the empty string.

In MATLAB, strings are row vectors of char and the only way to have an array in which each entry is a string, is to use a cell array.

Str = repmat(' ', 20, 72)

Note, that this is a string filled with spaces. An "empty" string has the dimensions [0 x 0].
