Make a new a directory and save a file in a loop

I am post-processing 36 different cases. What I want to do is run the script, save the variable of interest, create a new directory with the case number, then save the mat file and associated post-processing files in that new directory.

I am running into a problem with the save command. I am getting that I am passing in too many arguments. I'm not sure how I can specify the variable of interest that I am trying to save otherwise though. Any better ways to do this? Thanks for the help!

folder = 'C:Users\me\Documents'
for ind_bet=1:36
    run_analysis();         % run script
    save_plot_vars;         % script to save plotting variables
    fullFileName = sprintf('./plotvars_%d/plotvars_%d.mat', ind_bet);
    j{ind_bet} = save(fullFileName, 'plotvars');   % plot vars is the variable I want to save
    post()   % post processing script
    cd folder   % cd back to original directory and start over
end

use the following for saving data into a file.

save(fullFileName, 'plotvars');   % plot vars is the variable I want to save

The save() function does not return anything. So you cannot take it's output (of which there is none) and stuff it into j{ind_bet}. Perhaps you really wanted to save filenames???

j{ind_bet} = fullFileName; % Save this filename into a cell array.
save(fullFileName, 'plotvars'); % Don't accept any output arguments when you call save().
