... A matrix that has only one row is called a row matrix, and a matrix that has only one column is called a column matrix. A matrix derived from a system of linear equations (each written in standard form with the constant term on the right) is the augmented matrix of the system. Moreover, the matrix d ...

... First, if they are considered as matrices then you can multiply a row vector (1 x n) times a column vector (1 x n) in the same way that you multiply matrices when their dimensions are appropriate. Notice that, by the rule above, a (1 x n) times a (n x 1) has dimension (1 x 1), and thus is a scalar. ...

complexification of vector space
... representation of T with respect to these bases, then A, regarded as a complex matrix, is also the representation of T C with respect to the corresponding bases in V C and W C . So, the complexification process is a formal, coordinate-free way of saying: take the matrix A of T , with its real entrie ...

10.3 POWER METHOD FOR APPROXIMATING EIGENVALUES
... In this section you have seen the use of the power method to approximate the dominant eigenvalue of a matrix. This method can be modified to approximate other eigenvalues through use of a procedure called deflation. Moreover, the power method is only one of several techniques that can be used to app ...
