Chapter 9 - Linear Maps from (R^n) to (R^m)

Section 9.1 - Basics About Linear Maps

Example 9.1.6

u={2,5,-1};v={-7,1,3};w={4,-8,0};

M={u,v,w};

RowReduce[M]//MatrixForm

(B={{4,1,-2},{-9,6,10}})//MatrixForm

(A=B.Inverse[Transpose[M]])//MatrixForm

A.Transpose[M]//MatrixForm

Example 9.1.6 continued...

(W=Transpose[M])//MatrixForm

V=B;

V.Inverse[W]//MatrixForm
