how to load this function into simulink

here us 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

i am suppossed to give it a 1X5 matrix by which it will predict the output

when i do it in command line it works but when i do it in simulink i get errrors

making value is function that makes a 1X5 matrix

it is given by

function y=making_values_input(a,b,c,d,e)

y=[a,b,c,d,e]

end

when i run the simulation i get the following errrors

plz tell me what im doing wrong i have been stuck on it for 5 weeks help me on this

thanks

Hi arsal

Though not required, you can replace the function making_values_input with a Mux block.

Double click on predictActivity. In the editor, under the Function tab click on Edit Data. In the pane that opens you can click on y and u and explicitly specify the dimensions of each. relevant doc page

Maybe that will do the trick.

You also might need to declare the function predict() as extrinsic doc page

can u plz elobrate the last part

i sepcified the dimmensions now im getting these errors

Try to declare loadLearnerForCoder as extrinsic. Doc page in comment above.
