... We will use the definition above to define matrix transformations. Let A be a m × n matrix with real number entries. A matrix transformation is a Ax that maps vectors in n to vectors in m . function of the form f : x To illustrate, consider Maria's Optical Lab, which produces two types of lenses, po ...

Lecture 7: Definition of an Inverse Matrix and Examples
... Lecture 7: Definition of an Inverse Matrix and Examples In the previous lecture we gave examples of pairs of nxn matrices whose products were the identity matrix: the elementary matrices and the diagonal matrices with non-zero diagonal components. In the case of elementary matrices, these correspond ...
