Can't we embed function on our script? Must be at different one and just call them?

"Function definitions are not permitted at the prompt or in scripts"
The message seems quite clear to me: your version of MATLAB does not let you define a function inside a script, or in the command prompt. From version R2016b it is possible to define a function in a script.

You can use anonymous functions from the command line (or in a script). Compared to named functions, they are quite limited, though.
Example:
myfun = @(x) x.^3-2*x.^2+x-1
myfun(0:5)

Yes. Defining functions in script files was introduced in 2016b. If you have an older version, this does not work - exactly as the message tells you.
Must be at different one and just call them?
Yes. Or do not use a script file at all, but a function. In function files, the definition of subfunctions is allowed.
