Matrix multiplication, however, is quite another story. In fact, it's a royal pain. Your text probably gave you a complex formula for the process, and that formula probably didn't make any sense to you. That's okay. The process is messy, and that complicated formula is the best they can do for an explanation in a formal setting like a textbook 1. Create the arrays on the stack (including the 3x2 resulting matrix) 2. Read in the arrays (from file, console, etc) 3. For each row vector in the 3x3 matrix (first loop), and each column vector in the 3x2 matrix (second loop), compute the dot product The Strassen's method of matrix multiplication is a typical divide and conquer algorithm.

The inverse of a matrix is a matrix that multiplied by the original matrix results in the identity matrix, regardless of the order of the matrix multiplication.. Thus, let A be a square matrix, the inverse of matrix A is denoted by A-1 and satisfies:. A·A-1 =I. A-1 ·A=I. Where I is the identity matrix I've done some testing now, and made some improvement specifically for larger matrices (below N=64 it doesn't really help). Some results on Haswell, compiled with MSVC  2017, measuring the time (in cycles) per element of the result matrix (so you can mentally compare it to how much time it should take). Time results were eyeballed and rounded to a typical value
