Function definitions are not permitted in this context

Using Matlab R2017b, I can not define a function; I thought this was fixed in R2016b. Yes, I can define a script file.

>> function y = mydouble(x)
 function y = mydouble(x)

Error: Function definitions are not permitted in this context.

You appear to be trying to define a function in the Command Window. That isn't going to work, and I don't think it counts as something that "needs to be fixed."

I assume you're referring to local functions in scripts for the R2016b bit. You need to be in the editor (Live or otherwise) to create a script, then add a function declaration at the end.

What was "fixed" is that you are now allowed to define local functions in scripts. However, you cannot define functions (except anonymous functions) at the command line.
