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?

Hi @Dubravka Lekovic
The wiener and median filters that you created might not be working in C due to various reasons:
You may consider using “weiner2” and “medfilt1” rather than implementing them by yourself. Both functions are supported for code generation. Please refer to the following documentation for more info -
“weiner2” - https://www.mathworks.com/help/releases/R2022b/images/ref/wiener2.html
“medfilt1” - https://www.mathworks.com/help/releases/R2022b/signal/ref/medfilt1.html
