MATLAB: Matrix variable manipulation

faq 4.6strings

Hi,
I have a 3×1 string vector and a 3 by 3×3 matrix with values,
A= ['AAA';'BBB';'CCC'] B=[1 2 3;1 2 3;1 2 3]
what code can I use to create 3 new variables out of my string vector and assign them values from my matrix.
so that the result looks like this
AAA= [1;1;1] BBB= [2;2;2] CCC= [3;3;3]

Best Answer

You can use the "eval" command to do this:
A= ['AAA';'BBB';'CCC']
B=[1 2 3;1 2 3;1 2 3]
for ii = 1:3
   eval([A(ii,:),'=B(:,',num2str(ii),')']) 
end
If this is "real" code, as opposed to a school assignment, then this is almost certainly a poor approach to what you are trying to do. You might want to investigate "cell arrays".
