automatic filename saving

hi all, i cant seem to find what im looking for, if you had a simple function such as the one below, is it possible for matlab to automatically detect the file name to save it under?

function help

%user input data which will change each time

A = [1; 2; 3]; B = [1; 3; 3];

%save data

save("filename", A); save("filename", B);

end

is there a line of code which instead of the user specifying the name each time, for matlab to just save it under a different name each time the code is run and for different values of A and B thanks kyle

for ii = 1:n
 fn = sprintf('file_%s.jpg',num2str(ii,%04i')); %jpegs named file_0001.jpg, file_0002.jpg etc.
 save(fn,ii)
end

hi thanks for a speedy reply.. ive been trying to use the code, it will run and save the names once, but if i close down the program or rerun it for different variables then the file names dont continue to increase, as they would for example in a digital camera when taking pictures

You need to reinitialize your for loop if you want it to start higher.

thanks for your help

name = dir('data_*');

k = size(name);

for ii = (k(1)+1):(k(1)+2)

fn = sprintf('data_%s',num2str(ii,04i')); %jpegs named file_0001.jpg, file_0002.jpg etc.

save(fn,'deflection','int_force','-mat')

end

that was the code i ended up with and it works great thank you
