The docs for these functions describe what they do in pretty good detail. Given this, it should be pretty trivial to implement your own versions of these functions.

There are a couple places where the docs aren't accurate. Start with what's in the docs, compare your result to D3DX, and adjust your matrix calculations as appropriate. I seem to remember all the errors were trivial to fix.
