I have saved my trained SVM model using saveLearnerforCoder, and am trying to generate fixed point C code using codegen. However, I get the abover error using codegen.
saveLearnerForCoder(classificationSVM,'Classifier_FP');
generateLearnerDataTypeFcn('Classifier_FP',predictor_data);
T = Classifier_FP_datatype('Fixed')
X_fx = cast(predictor_data,'like',T.XDataType);
codegen EntryPointFcn -args {X_fx,coder.Constant(T)}
The error points to the line validateattributes in a built in function validateFields(Instr). How can I fix this issue?
