How to save workspace variables and values a s binary file

3 views (last 30 days)
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.

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

Great, Thanks for the help. There is still one problem. Is there any way to print out the value of either of the variables just right in front of the variables' names to the command window?

fprintf('%f is the value for %s.\n', thisValue, thisVariable);
