As far as I know, matrices cannot be divided, you have to multiply one matrix by the inverse of the other...I believe. However, I am converting MatLab code into ANSI C and MatLab apparently divides two matrices. An example is the following... >>A=[1.5708 1.5708]; B=[0.4937 0.7652]; A/B ans = 2.3846 I have no idea how MatLab generated this answer. I try to find the inverse of the second matrix, but since it is a non-square matrix, MatLab denies my request. Can anyone aid me in figuring out how such an answer was calculated? Thank you in advance.
