Introduction to Matrices
... on the right. In this way, the transformation will read like a sentence. This is especially important when more than one transformation takes place. For example, if we wish to transform a vector v by the matrices A, B, and C, in that order, we write vABC. Notice that the matrices are listed in order ...
