where bi is a vector of zeros except at position i where it has 1, and xi is the ith column of the inverse. Using this formulation write a Python function that computes the inverse of a general n×n matrix. There are two ways of doing this, one way computes Gaussian elimination n ti...
gives the correct results but (a) Matlab suggest not doing so (although the backward slash gives the wrong results) and (b) I've always avoided multiplying by the inverse of a matrix due to potential inaccuracy. Is there a better way?
