Removed Support for Certain Functions in MATLAB Grader?
4 views (last 30 days)
I am reusing a MATLAB Grader assignment from previous semesters for my students this term, and it seems like some functions are no longer supported. In the below code, view() and train() are no longer supported, but were supported in the past.
%% compare with patternnet
net = patternnet(4,'trainscg','crossentropy');
net = configure(net,X,Y);
%% output from randomly initialized net
net = init(net);
Yest = sim(net,X);
%% train it!
net.trainParam.max_fail = 200;
%net.trainParam.epochs = 10000;
[trainedNet, history] = train(net, X, Y);
Are there release notes for the list of functions or toolboxes the current MATLAB Grader version supports and no longer supports?

The error I get when running a similar example in Grader is
Error using matlab.internal.lang.capability.Capability.require
This functionality is not available on remote platforms.
The view and train commands call interactive elements that are not supported in MATLAB Grader. If this used to work, then it appears a new check has been added that does not explicitly ban the use of these two functions, but does throw an error whenever interactive elements are called within Grader. I suggest reporting this change in functionality to MathWorks Support so they can investigate further.

When creating your new course, did you remember to add the required toolboxes to your course? What MATLAB error messages do you see when you run your code? If it says function could not be found, you most likely need to add the toolboxes you require on your course settings.
