Coder.ceval function is not working when calling a C Library function

Hallo everybody ,

im trying to accelerate my Program on App designer by calling imfilter over a C code (assumed that it would be faster on a c code).

i used Codgen to generate the c library and then called it back using coder.ceval. unfortionatly MATLAB keeps giving me an error back that coder.Ceval is not supported in Matlab.

here is an Screenshot i took it after running the Code

can anyone Help ?

thanks a lot in Advance

coder.ceval is not to be used in MATLAB simulation workflow. It is to be used only when you want to integrate external C code for code generation workflow. For your use case, isolate the coder.include and coder.ceval calls to new function and create a MEX for that function using coder and use the generated mex instead of coder.ceval.
