Why wiener and median filter doesnt work after convert with embedded coder in c language?

Hello,

I am using wiener and median filter to remove gaussian noise in c language. My project use real sound and add gaussian noise then filtering with both fiter. I created matlab function for gaussian noise and both filter. I am using embedded coder to convert matlab function to c language and when i use that c code in my project both filter not work. When i convert gaussian noise everithing work fine but when i convert both filter same way, they dont work. My function is very simple only input, output and wiener and median matlab function. How can i fix this problem?
