How can i calculate the center of mass ?

Hello every one

i want to calculate the center of mass for 3 Matrix.I have a file of CAD then i have to transfer it to Matlab file by STL File. In Matlab i get 3 Matrix , one for X axi, one for Y and one for Z. How can i calculate the center of mass ?

Do you know how to find volume?

What is the code you currently have and how did you try to implement my answer?

You can use the VOXELISE function to convert your mesh to a voxelgrid. Use a resolution that makes the most sense to you: too few will decrease your accuracy, too many will cause memory issues. I would suggest picking z-values that do not occur in your mesh, but that is optional.

Then you will have a 3D logical array. You can use findND to get the coordinates of all your voxels: [x,y,z]=findND(L);

The last step is to find the mean values of x,y,z.
