How to save workspace variables and values a s binary file
显示 更早的评论
I wrote a code and want to save all workspace's variables and their values as a .txt file or other formats as a binary file just to print them out. Note I need both variable names and values.

This can be tricky when you start getting into graphics objects, or cell arrays, or non-scalar struct especially if not all the descendants have the same fields... And how would you like arrays with 3 or more dimensions to be output?

Are all of the variables pure numeric? Are they all row vectors? Are some of them 2D arrays? Are some of them 3D arrays?

Try this and see if it does what you want:
% Get list of all variables in current workspace.
s = whos
% Print out variables one by one to the command window.
% Essentially we're using eval() to put each variable on the command line.
% When you do that, MATLAB will report the value to the command line,
% just as if you had manually typed the variable name yourself on the command line.
for k = 1 : length(s)
thisVariable = s(k).name;
eval(thisVariable)
end
