Sort 3D data into Bins
显示 更早的评论
Hi,
I have a matrix containing 3D position data. i.e. The first row of "A" contains the first X,Y and Z coordinate of a point. I want to create a 3D matrix (say 150 x 150 x 150 elements) and sort the positional data into these voxels. The 3D matrix elements would contain the number of points that lie in that voxel.
I'm currently using three for loops which is very slow.
Any ideas that are more efficient?
Thanks

If you post the existing code, it is easier to create a suggestion for improvements.
