this is the error msg that I got :
The function 'AppDec_Fun2' contains persistent variables 'dataAppFun2' and has specialization 'AppDec_Fun2_s1' associated with it. Function specializations containing persistent variables are not supported for fixed-point conversion. Consider rewriting your algorithm such that it does not use persistent variables within functions that require specialization.

Memory Store perhaps ?
Or you could probably avoid the problem by coding the function in fixed-point yourself, so that it did not need to be specialized to convert from double to fixed point.

Can you share a sample design.m, testbench.m and project file used for fixed point conversion?
Thanks

The function 'AppDec_Fun2'is not my principale function from wich I'm generating HDL code. I gave its matlab code in previous comments.
