create a function in matlab that sums two m x n matrices using nested loops, then returns result into a new matrix. Use nesed for loops to add matrices piece by piece. Basically means, dont program simply A+B Function should perform error check to make sure both matrices have same number of rows/ columns.

prove the following statement: If the augmented matrices of two linear systems are row equivalent, then those systems are equivalent. (To do this, start with a solution to one of the systems and show that it is still a solution of the other system under each of the three elementary row operations.)
