Row Reduction using GaussJordan Elimination  In this worksheet, the user enters the coefficients for a $MxN$ linear system. The intermediate steps for perfoming GaussJordan Elimination are output. The user can choose a random matrix of given dimension or enter a specific matrix. The user can also choose to perform only regular echelon form where only the entries below the main diagonal are zeroed out.

Assignment...using the cells below, create a 4x5 problem where the worksheet creates the matrix randomly. Then, write out the elimination commands needed for each of step along the way in reducing the original matrix to reduced row echelon formRREF. Put your answers at the bottom of this worksheet with the commands for each stage in a different text box.
For example, you might write:
Step 1:
$3*R_1+R_3\rightarrow R_3$ , or without using latex and just using text, 3 R1 + R3 > R3
blah, blah, blah
Step 2:
blah, blah, blah
For your system, first select the number of rows and columns.
