use Extrinsic function in Embedded Matlab Function of Simulink

I create function of TriScatteredInterp 'name of AFUNCTION' in MATLAB.

But my program is basically based on simulink. so, I wanna call this TriScatteredInterp function by embedded MATLAB Function icon. Thus, I make

=======================

function y = fcn(u1,u2)

%#eml

eml.extrinsic('AFUNCTION');

y = feval('AFUNCTION',u1,u2);

=============================

But there is an error message. 'Function output 'y' cannot be of MATLAB type' I've learned about this output type so if output type is a double, I can correct this problem by adding y=0; (y is scalar of type double)

then what can I correct the problem about the value of TriScatteredInterp?

y = feval('AFUNCTION',u1,u2) has an output A type of TriScatteredInterp

The Embedded MATLAB Function block only allows inputs/outputs of numeric types - TriScatteredInterp is not a supported type.

Could you explain why you would like to output an object of type TriScatteredInterp? Note that you cannot output such a signal to Simulink because only numeric signals are allowed. Perhaps you should modify your design such that you output only numeric values.

Thank you for your answer.

I didn't realize about allowable signal in simulink.

I think I have to modify my design.

Thanks again.
