MATLAB: How to list variables in save() as an array of strings

Question

I want to save a list of vars to a mat file, but the list of vars is not known until run time, such as:

vars = ['a', 'b', 'c']; save('fname', vars)

Is this possible?

Answer 1

use a cell array,

 vars = {'a','b','c'};

and then,

 save('dummy.mat',vars{:})
