148 First of all, make sure that you really want this. While inverse and determinant are fundamental mathematical concepts,
150 advantageously replaced by solve() operations, and the determinant is often \em not a good way of checking if a matrix
153 However, for \em very \em small matrices, the above is not true, and inverse and determinant can be very useful.
155 While certain decompositions, such as PartialPivLU and FullPivLU, offer inverse() and determinant() methods, you can also
156 call inverse() and determinant() directly on a matrix. If your matrix is of a very small fixed size (at most 4x4) this
