How can i save multiple variables in a text file, including the variable names

I have a workspace with 30 variables, all sized 8x1.

I would like to save all of them in a .txt file, including their name.

The command I am using is:

save( 'filename.txt' , '-ASCII' );

It saves the variable values as intended, but not the variable names alongside their values.

Any help would be most welcome! Thank you in advance!

why don' t save them to mat file? is there any reason?

not op, but my code generated around 50 variables. I would love to have a snapshot of them and look at them later (it doesn't matter for me to save the details of structures/matrixes). I don't want them to be in .mat format because I don't want to override the workspace generated by a slightly different code. I can print the workspace to pdf, but saving them with a txt file would be nicer. I did this one but now I now forget how to do that.

 myfilepath = 'C:\myfile.txt';

 fid = fopen(myfilepath, 'wt');

 fprintf(fid, '% this is the beginning of my file');

 fprintf(fid, 'var1 = %d ',evalin('base',var1));  % if var1 is double

 fclose(fid);

you can use "whos" to find what variables u have in base workspace...
