save_to_base.m

copies variables from the workspace of the calling function to the base workspace

Description

save_to_base() copies variables in the workspace of the calling function to the base workspace. This makes it possible to examine a function's internal variables from the Matlab command prompt after the calling function terminates.

If the optional argument "overwrite" is present and has a non-zero value, variables in the workspace of the caller will overwrite variables in the base workspace having the same name. Otherwise, preexisting variables in the base workspace will not be overwritten.

I found trouble when I had a stray "ans" variable floating around. I got this message:

??? The variable "ans" is undefined.

To avoid trying to copy "ans", I modified save_to_base.m so that the for loop now reads:

for i= 1 : length(variables)
    if ~strcmp(variables{i},'ans')
        tmp= evalin('caller',variables{i});
        assignin('base',variables{i},tmp);
    end
end

Very nice little function.
