ArrayMesh
ArrayMesh [array]
generates a mesh region from an array of rank d in which each cell has a geometric dimension d and represents a nonzero value of the array.
Details and Options
- ArrayMesh is generated from a grid where cells are intervals, squares, or cubes, and grid points are uniformly spaced integer points.
- ArrayMesh arranges successive rows of array down and successive columns across.
- ArrayMesh has the same options as MeshRegion , with the following additions:
- ArrayMesh works with SparseArray objects.
