the following equations can be represented by matrix A and vector b
a b
xxxxxxxxx
Use the command rrefto place the augmented matrix in reduced row echelon form to solve for x Store the final results of x x x in an array or vector called x
Another way to solve the above system is to apply the following formula, where A is the inverse matrix of A
A Ax Ab
Use the above relationship to solve for x Remember the product of AA gives you the identity matrix. The answers that you obtained in b should be same as the answers in a
