Hi everyone,

I am looking for a Matlab Tool/Function that provides surface roughness values (Sa,Sz,W), out of an input vector that contains information about the real structure of the measured component. The Tool must be according to ISO 25178 or rather filtration must be according to ISO 16610-21.

Note: Output values should not be Ra,Rz values but rather Sa,Sz values.

I have found the following surface metrology tool:

https://de.mathworks.com/matlabcentral/fileexchange/52892-surface-metrology-open-profile-gaussian-filter?s_tid=srchtitle

Basically the tool uses gaussians filters to determine waviness and roughness out of the primary structure (see attached Figure). So this is part of the solution I am looking for. What remains is the ISO filtration of the real values to the primary values.

Is there any Matlab tool that does that or even better a tool which combines both filter viz. performs the whole filtration pictured in the attached figure?

Thanks in advance!
