I'm trying to understand OpenGL's matrix implementation. The spec suggests
m[16] instead of m[i][j]. Seeing that an array starts at 0, are we discarding
m[0] or m[16]?

If you declare an array like m[16] in C [this is not secific toOpenGL], the only valid index values are 0 to 15. Accessing m[16] is a no-no. So under C, you "discard" m[16].
