This is my Matlab Code
%#codegen
function y = neha(data)
Persistent hMod hDemod;
if isempty(hMOd)
hMod = comm.BPSKModulator;
hDemod = comm.BPSKDemodulator;
end
modSignal = step(hMod, data);
y = step(hDemod, modSignal);
end
This is my Test Bench
clear neha;
x=[1 0 1 0 1 0 1 1 0 0 1 ]
len=size(x)
y=zeros(1,len);
for ii=1:len
data =x(ii);
y(ii) = neha(data);
end
I have validate the code. But while conversion into VHDL I am getting this error
neha FixPt:15 - error - Single and Double Data Types are not supported in HDL conversion

Sir, I am not indexing the array by 0. Its starting from 1 till length. As mentioned, the error is related to Single and Double Data Types. Pls. give your valuable suggestions.

Ah I was getting function calls and indexing confused. In any case see the Answer I gave.

x = uint8([1 0 1 0 1 0 1 1 0 0 1 ]);
and
y = zeros(1, len, class(x));
