Greets! I am using MATLAB for my Final Year Project. I just want to ask what is meant by Error: Function definitions are not permitted in this context. This is the first part of the coding. It says that function facetest | Error: Function definitions are not permitted in this context.
I already save the file as facetest.m and it appear the same error. Can anyone teach me how to solve this problem? Thanks

The error means that you are not permitted to define a function file inside a script file. Create your ‘facetest’ as a separate file in the MATLAB Editor(open a new tab) and then save it as facetest.m. See the documentation on Function Basics for details.
