How do I convert all the 'single' type variables in my workspace to 'double'?

I need to convert all the 'single' variables in my workspace to 'double'. However, I do not want to use the function DOUBLE on every variable. I would like a small piece of code in my file, that can ensure that all the variables have been set to type 'double'.

The following example demonstrates a way to do this in MATLAB.

s = whos;

for i = 1:length(s)

      if strcmp(s(i).class,'single')

          name = s(i).name;

          assignin('base', name, double(evalin('base', name)));

      end

end

This code, upon execution, searches for any 'single' types in the current workspace, and converts them to 'double'.
