Unfortunately, this function is not in the list of MATLAB functions supported for code generation. You might need to implement a C-equivalent yourself (or try to find an equivalent third-part library function), and integrate it into a custom Simulink block.

But this is not straight forward, i have heard that there is a command something like "external command" that can help with this issue, but i am not sure how.

pemfir: Do you mean using coder.extrinsic? That only works if your block is executing within the MATLAB environment, it does not generate standalone code which is what Simulink Coder does.

how do i go about doing the C-equivalent, can you help me get started ?

pemfir: Sorry, I have no experience in this area. You might want to get help from Statistics experts/forums.

Thank you, what i mean, is that a simple example of such implementation, it does not have to be normcdf, any function would be good, so i can get started.
