matlab function to simulink error

here is code for the machine learning function

function y = predictActivity(u)%#codegen

persistent n;

if isempty(n)

n = loadLearnerForCoder('EnsembleModel.mat');

end

y = predict(n,u);

end

whenever i use it on command line it works fine

i make its block in simulink like this

but when run its block in simulink i get many errors like this

plz someone help me in this i have been stuck on this for quite a while

thnx in advance

It looks like you are using a "MATLAB Function" block.

Can you please provide the code that is inside of that block.

I think it looks like you are not using the "MATLAB Function" block correctly.

If you open that block, maybe you just have the single line of code:

function y = PredictActiity(u)

If so, this is not correct. You need to have a body for the function you define, so you would need to have something like

function y = myfun(u)
y = PredictActiity(u)

While the above should work, it would be simpler to use the "Interpreted MATLAB Function" block.

In this case you would double click on the Interpreted MATLAB Fcn block and enter in the dialog where it asks for MATLAB function:

PredictActiity(u)
