The Wikipedia article on matrix inverse lists 14 different algorithms, and each algorithm has multiple variations, and each variation has dozens of implementation alternatives. Four examples include 1 ...

For example, the inverse of 4 is 0.25 because 4 * 0.25 = 1. There are several algorithms to compute a matrix inverse, and each algorithm has several variations. Three common algorithms are LUP ("lower ...

Higher-order singular value decomposition (HOSVD) is an efficient way for data reduction and also eliciting intrinsic structure of multi-dimensional array data. It has been used in many applications, ...
