XIn this activity you wil1 use the rref() command to find the reduced row echelon form of a matrix Kand represent results as ratios. *Create the matrix A. A=[213;1:07;6;5.4] [rowredacedA, pivotvarsA] =rref(A) Wuse the "format rat" option to express elements as ratios.) format rat [rowreducedA, pivatvarsA] =rref(A) Use the following matrox for this activily. C=212122303137 Script DI MATLAB Documontation 1. XCreate the matrix C. Wise the rref() comand to reduce the matrix C; Store the reduced matrix in rovreducedc, and Xstore the pivot variables in pivotvarsc. Wuse the "foreat rat." option to exgress eleeents as rat ios
