I have a set of data points in 3D space (a matrix of (n x 3), in which each row corresponds to a point) that are extracted from a stl file and all together describe an irregular surface. I want to find the extrema of this surface. Is there anyway to do this in matlab? Attached is a sample file.
I know using the approach described in the following post we can find the extrema but the problem is that my data points are not continous and I cannot use meshgrid.
