Gauss-Jordan elimination method for inverse matrix

[tubar]

I try in Mathcad to build  Gauss-Jordan method for obtaining the inverse matrix but it looks quite difficult.

It is closed to Jordan elimination method, but on the right side we consider initially (in the augmented matrix) an unit matrix. Did anyone build this method in Mathcad?

You have to tell Mathcad to show nested matrices in the result.

Double click the result or chose "Format"-"Result" from the menu and active tab "Display Options" and check "Expand nested arrays".

The {2,4} represents the information that the element is a matrix with 2 rows and 4 columns.

Cool ! I see that it makes also Pivotation. The problem is solved !  I attached the file.

This is so simple in Mathcad 15, and Prime and the method is built in

If "K" is the matrix then type K^-1= to get the numeric inverse.
