Control function during execusion with command line

Hi,

is there a way to control and stop a function with the command line? How can I create an interface to the user? Using 'disp()' it is easy to display Error and Execusion messages, but there is no way, to control the function process.

For example, I want to display: 'The statistics of your function are [..]. Do you want to proceed? [Y/N]'

The only way to stop a running function, which I know, is the close the whole programm. It is possible, the create a complete GUI to control a function execusion, but I am looking for a more simple way.

best regards
