Functions can be defined in "function files" only: Files which start with the expression "function". There you can define a main function (called as the file), sub-functions, which are visible for the main-function also, and nested functions, which are visible for the parent function.

You cannot define functions inside scripts (M-files which donot start with "function") or in the command line.

Note: This topic has been discussed repeatedly and searchuing in the forum or the internet for the error message would reveal a solution very fast.
