Cross in Matrix

[mlpalacios8]

Handling matrixes is more efficient in the Prime than in the 50g.

I recommend you to use CAS and the matrix templates.

Put the command and then manually enter the matrix using the matrix template (1st row, last column).
The comma button serves as a "next column".

This is very helpful to solve linear system of equations too (inverse coefficient matrix * contant matrix, RREF command, etc).

After a couple of minutes, you will see how efficient the Prime is with matrixes thanks to the big touchscreen.
