Hello,
I want to measure the Hausdorff-Distance between two STL meshes. Is it possible to import the STL-Data and convert it in matrix where every point has its x,y,z-coordinate?
Thanks!

What about using Matlab's STL import?

Try stlread to import geometry
Use griddata to interpolate data

stlread() does in fact still work, but stlread(), stlread(), stlread(), stlread(), and stlRead() also still work. The problem is that there is the one that's been built into MATLAB since R2018b, and then there are similarly-named tools from the File Exchange that everyone keeps downloading based on ancient advice and random code snippets on the forum.
The various tools don't all have the same functionality, and they don't all return the same type of output data. Either use the tool your code is written for, or write your code to suit the tool you're using.
