Dynamically Assign Variables in Matlab

Question

I have the following function as part of a large codebase, which I inherited:

function = save_function(fpath, a,b,c)
    save(fpath, \'a\', \'b\', \'c\')
end         


        

Answer 1

You can use a structure to dynamically define saved variable names.
This option is documented here.

 function save_function( fpath, varargin )     
 for ii = 1:numel( varargin )
     st.( inputname(ii+1) ) = varargin{ii};
 end
 save( fpath, '-struct', 'st' );

As a rule of thumb, structure with dynamic field names is often better than eval or assignin when it comes to dynamic variable names.

PS,
It is best not to use i as variable name in Matlab.
