Perform row operations in MATLAB that reduce the matrix A to Row Echelon Form.

The row operations are indicated for you in the learner template. Make sure you follow the instructions and perform only the row operation indicated in the comments. After each row operation, the result is stored in a new matrix in order for MATLAB to verify the accuracy of the intermediate steps.

You might want to click on "Run Script" at each row operations to check that your steps are correct and to determine the next step in the row reduction.

NOTE: in format rat, a number very close to zero, but not exactly zero due to round off error is denoted by $*.$ If you see $*$ in the output of your calculations, you should treat it as zero.
