How about assigning a space to str_vect before the string you put in
it?

% Matrix of numbers.
num_mat=[1,2,10;25,2,1;10,9,21];

% Coulmn vector of string, X.
for i = 1:size(num_mat,1)
str_vect(i,1)=' X';
end

% Required matrix.
Req_mat=[num2str(num_mat),str_vect]
%%%%%%%%%%%%%%%%%%%%%
Req_mat =

1 2 10 X
25 2 1 X
10 9 21 X

Hi Nathan,

I did try to assign a space to the string, but I get this error....(i guess this is what you meant me to do?)

for i=1:size(num_mat,1)
str_vect(i,1)=' X'; %Space given before X.
end
??? Subscripted assignment dimension mismatch.

If "str_vect" already exists before the loop, you might get the mentioned error (if size and anture of the variable aren't coherent with the assignment).

Hi Oleg,

Thanks for giving me the hint :-) I realised now that when I give a space before the string, the no. of columns in the matrix is no longer 1! But it is actually 2 :-) Such a silly one, but I had just overlooked it. Thanks for this.

for i=1:size(num_mat,1)
str_vect(i,1:2)=' X'; %Space given before X.
end

Many thanks to Nathan as well for all the inputs.

Thanks,
Vinod Karanth
