Kopia av Operations on ONE matrix

Transpose, inverse, scalar multiple, determinant, and finding reduced row echelon form of square matrices require only one. (I think the inverse problems are doable-thanks to a method from an article by R. Hanson, Integer Matrices Whose Inverse Contain Only Integers, The Two-Year College Mathematics Journal, Vol. 13, No. 1 (Jan., 1982), pp. 18-21.)
