This is in C++ Code
Hello im currently trying to finish one of my programs for class im having a small problem iv been trying to code this for 10+ hours now but im currently trying to get my 3x3 * 3x1 to work but i cant seem to get it to work. Im getting some of my code out of the book but here it is.
This is in my MathLib.h file i need to be able to use these functions to muliply other matrices.
