The MATLAB function in the simulink model creates two circular buffers named as 'circBuff_In' and 'circBuff_PA' to store the input signal.But the linearizeer function is using different variable names which is causing the issue.
The MATLAB function code can be updated to use the correct variable names as given below
function Output = lin_Fun(In_1,In_2)
coder.extrinsic('Linearizer');
Output= 0;
persistent circBuff_In;
persistent circBuff_PA;
if isempty(circBuff_In)
circBuff_In = zeros(1,10);
end
if isempty(circBuff_PA)
circBuff_PA = zeros(1,10);
end
global N;
global n;
Output = circBuff_In(1)+circBuff_PA(1);
circBuff_In = [In_1 circBuff_In(1:end-1)];
circBuff_PA = [In_2 circBuff_PA(1:end-1)];
end
The figure below shows the result of the spectrum analyzer
Hope this would resolve the issue!
