PPT-Multiply Matrices Chapter 3.6

Matrix Multiplication Matrix multiplication is defined differently than matrix addition The matrices need not be of the same dimension Multiplication of the elements will involve both multiplication and addition. Positive de64257nite matrices ar e even bet ter Symmetric matrices A symmetric matrix is one for which A T If a matrix has some special pr operty eg its a Markov matrix its eigenvalues and eigenvectors ar e likely to have special pr operties as we It is essential that you do some reading but the topics discussed in this chapter are adequately covered in so many texts on linear algebra that it would be arti64257cial and unnecessarily limiting to specify precise passages from precise texts The Section 1.6.
