Error: Function definitions are not supported in this context. Functions can only be created as local or nested functions in code files.

What's the purpose of the line ?

[Aquatris]

Matlab expects functions to be defined as:

function y = myFun(x)
%% YOUR FUNCTION GOES HERE %%
end

Also, within a script, they can only be defined in this way at the end of the script.

[Taylor]

As stated, functions in MATLAB must be defined as:

function y = myFunc(x)
%% Do something
end

If the function is in a file by itself, the file name must be the function name. Terminating with an "end" statement is optional in this case. If the function is defined within a script, it may be placed anywhere as of R2024a.
