Hi everyone. I am converting mexFunction to general c/c++ function, so that it can be called in another c/c++ function. I think it's the problem dealing with arguments. How can i do it? Thanks in advance.

There are two arguments. One is image array, other is kernel. I am doing convolution with them. So, those are mutidimensional array. Would you put the code here for detail explanation?

A clean Mex function uses the mexFunction() function to obtain the pointers to the values of the inputs at first. Then a subsection, or better sub-functions process the data. Finally the mexFunction() creates the outputs for Matlab.
Then it is relatively easy to remove the mexFunction() and use the sub-function for calculations from otehr C-code directly.
But maybe the mexFunction() creates the outputs at first and delivers pointers to allocated arrays to the subfunction. Or the mexFunction() mixes its job as a Matlab-C-gateway with calculations. Then a separation of the Mex and C parts is difficult.
