Hi i have an issue with a regressionlearner Model that i trained with the App --> saved Model or compact model and try to use MatlabFunction in Simulink and get Errors.
function y = fcn(x1,x2,x3,x4,x5)
y = trainedModel08072019.predictFcn(x1,x2,x3,x4,x5);
This is the Error I get from Matlab:
Undefined function or variable 'trainedModel08072019'.
Function 'MATLAB Function' (#128.38.58), line 3, column 5:
"trainedModel08072019"
Launch diagnostic report.
Component:MATLAB Function | Category:Coder error
Errors occurred during parsing of MATLAB function 'TrainedModel_test/MATLAB Function'
Component:MATLAB Function | Category:Coder error
Simulink cannot determine sizes and/or types of the outputs for block 'TrainedModel_test/MATLAB Function' due to errors in the block body, or limitations of the underlying analysis. The errors might be inaccurate. Fix the indicated errors, or explicitly specify sizes and/or types for all block outputs.

Hi Tugce,
I have a similar problem for the implementation of an exported trainedClassifier in Simulink.
Have you been able to solve the issue?
