hey how can I add a string in matrix?
ex.
for i=1:5
A(i)=i+1;
end
mat2str(A);

A=[1 2 3 4]
B=[ num2cell(A) 'A']

A = sprintf('%i',1:5); % Make a character array.
A(6) = 'B'
If you must have spaces, then you must be more careful about how you index into A. A character array counts the spaces as elements!
A = sprintf('%i ',1:5);
A(11) = 'B'
