An Excel-based matrix calculator for integer matrices having at most four rows/columns

Описание к видео An Excel-based matrix calculator for integer matrices having at most four rows/columns

In this video we introduce our excel-based matrix calculator for integer matrices having at most four rows/columns. The calculator appearing in the video has been revised extensively. The revised calculator now calculates the rank of a matrix also, apart from already mentioned adjoint, determinant, inverse, sum, difference, scalar multiple and product of matrices. Moreover, the entries of the inverse appear as fractions and there is no approximations. The revised version of the calculator looks a bit different and can be downloaded from the following links, but don't forget to subscribe my channel:
