use cell aray

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

%or

A=num2cell(A)
A{5}='A'

thanks man, this would work but, I need to convert this to str so I can use strcat().. and now im wondering about that.

[Matt J]

[A+'0','A']

or

[num2str(A), '  A']

[jelly]

with a triple space? in num2str?

[Azzi Abdelmalek]

jelly what do you want exactly?

[Dursun ÖNER]

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'
