You cannot do that. Numeric matrices cannot have spaces in them.
You can convert the matrix into a cell array and put spaces into the cell array... but it is not clear why you would do that.
myCell = num2cell(MyMatrix);
myCell(isnan(MyMatrix)) = {' '}; %nan -> space
Now what?

Ok perfect, it works! Really really thank you!
The last doubt: do you know how to replace a number that has a lower number of digits with respect to the other numbers in the matrix with the same number with zero digits in order to have the same format of the other numbers? For instance, if I have a “1” in a matrix where all the other numbers are decimal with 4 decimal digits, how can I transform it into “1.0000”?
