can you please create a 3D matrix (i.e. imagine it as a cube of 10 x 10 x 10 voxels) and then set all voxels on the edges to have a value of 1 and all the internal voxels to have a value of 0 Then calculate the ratio of voxels set to “1” versus “0”) And finally, can you export the 3D voxel matrix to an STL file.

Hi,

In MATLAB, you can easily create 3-D matrix by concatenating multiple 2-D matrices. Multidimensional arrays are an extension to 2D matrices. I am attaching the link below for the documentation of multidimensional arrays,

For creating STL file from a 3-D voxel matrix you can refer the below link.
