In MATLAB, why does the file have to be saved prior to running ?
I often try quick snippets of code, which I could also easily run also on the Command Window line by line. So, why when I run them through the editor, I have to save them first ?
Can this behaviour be changed, maybe ?
You can use cell mode in the editor placing %% before your code. See also Cell menu in the editor. Once you create cells, you can run them one by one pressing Ctrl-Enter. You don’t need to save the file. However you cannot use editor’s debugging features (breakpoints, etc).
