MATLAB: How to create and save a variable that contains filename

Question

I would like to create and save a variable that contains the file number given in a string, for example:

file='1';
 a=[1 2 3];
name = ['a' num2str(file), '=a'];
eval(name);

which creates a1=[1 2 3]

How can I now save this variable a1 in a mat file (without need to write a1, because this should work in a for loop, where 1 in incremented) ? Thanks

Answer 1

name='a1'
save('yourmatfile',name)

But this is not a good idea, if you explain what you want to achieve, maybe there are better ways.
