What is the best way to index an n-dimensional matrix, if I have a vector of
n indices?

If I have a 2D matrix M, and vector [j,k], I want M(j,k).
If I have a 3D matrix M, and vector [j,k,m], I want M(j,k,m).

I know that if I just do M([j,k,m]), I'll get three elements back.

Apologies if this is clearly stated in some document-- I've looked, but I'm
not finding a reference to this particular problem.

Did you try M(j,k,m)?
