- Aardwolf 3y agoIt's to multiply a matrix by the inverse of another. There's left and right division depending on which side is inverted There are many more matrix operations that actually exist: matrix exponential, matrix log, matrix trig functions, matrix square root, ... E.g. exponential has an infinite series representation exp(x) = SUM_k x^k / k!: it works for matrices too, and is used
