Each row of k defines a triangle in terms of the point indices, and the triangles collectively form a bounding polyhedron. Here's a code snippet demonstrating how to use the `fill` function: Matlab documentation states that "a hole is a set of background pixels that cannot be reached by filling in the background from the edge of the image". To suppress the small holes in the alpha shape, you can specify a HoleThreshold by estimating the area of the largest hole to fill. This algorithm works only if the color with which the region has to be filled and the color of the boundary of the region are different. Trying to shade a region between my data points.
