Hi, I have 2 .ply files. I would like to compare differencies between two shapes (where are the maximal differencies between surfaces). I loaded two files to Workspace. Next, some of points were errors, then I deleted them (z values < -900) and I have two almost the same matrices (XYZ coordinates). The first matrix is 263000x3, the second 248000x3. How compare these shapes and show in figure? Thanks a lot

Just a suggestion: don't delete the erroneous entries; instead set them to NaN. That way I assume that all the relevant entries will retain the same subscripts in both matrices (as both matrices should have the same dimensions).
