i have problem to call the neural network tha has been trained, in matlab simulink function block.

as you know after training the nueralnetwork, the object, the name is ''net'' will be create , and it works in workspace when you call ''net'' with an argument. but if i call it in a matlab function in simulink, i see:

Undefined function or variable 'net'.

Function 'DC//DC 1/MPPT Control 2 nueral network' (#186.1601.1615), line 77, column 4:

"net([Irr;tmp])"

Launch diagnostic report.

Hi Alireza,

As I see, you have a workspace variable which you want to use in the MATLAB Function block. The error is because the variable is not visible to the Simulink Model.

I think the following MATLAB Answers queries can be of use to you:

Hope this helps you.
