Saving workspace via command

I have written code to produce 30 (approx) numeric matrices, all of which I wish to save to a given directory under a single .mat name. What code can be written within the script to save the entire workspace automatically?

Answer 1

[Walter Roberson]

save('NameOfFileToSaveTo.mat')

[Sam Hurrell]

That saves the workspace to the current folder, how would I save it to a defined location?
