For this week's laboratory, you will write four linear algebra functions using

for$-$loops or while$-$loops. The four linear algebra functions you will write are

calculating the magnitude of a vector, $2$Ax$=$biAB$=$C b$,$ and the result from the matrix$-$matrix multiply, which is the

matrix C x$\_(1)=[[8],[2],[10],[17]]$ and x$\_(2)=[[1],[30],[11],[6]].,$A$=[[-4,15,2,7],[1,8,21,12],[10,6,11,14],[17,9,4,23]],$ and B$=[[5,17,6,3],[20,9,27,1],[11,2,23,24],[8,24,2,27]]$
