Hi All,
I am looking for analyzing the surface roughness both 2D and 3D from set of coordinate values. Is there any tool in MATLAB that can help me plot roughness profiles (2D and 3D) and measure the profile parameters such as Ra, Rz, Rt, etc.? Please help me if you have any MATLAB code to do this.
With regards, Uma Shankar

@Mohannad Alsheikh Essa, again "Yes", just like I told @Avdheshkumar Kakadiya earlier. Did either of you see my answer below? It was accepted. The formulas are simple to implement with the functions I listed. You could also see immse().

You can use functions like sqrt(), mean(), etc. Most of the formulas are pretty simple.

What about the extraction and waveness though? The roughness measurement would be wrong if the waveness is not removed from the main profile.
