Notice that the equation (x⋅I-A)⋅p(x)=m(x)⋅I is similar, in form, to the

eigenvalue equation A⋅x = λ⋅x.

As an example, in RPN mode, try:

[[4,1,-2] [1,2,-1][-2,-1,0]] M D

The result is:

3: [[ 0.13 –0.25 –0.38][-0.25 0.50 –0.25][-0.38 –0.25 –0.88]]

2: {[[1 0 0][0 1 0][0 0 1]] [[ -2 1 –2][1 –4 –1][-2 –1 –6] [[-1 2 3][2 –4 2][3 2 7]]}

1: ‘X^3+-6*x^2+2*X+8’

The same exercise, in ALG mode, will look as follows:

Matrix factorization

Matrix factorization or decomposition consists of obtaining matrices that when

multiplied result in a given matrix. We present matrix decomposition through

the use of Functions contained in the matrix FACT menu. This menu is accessed

Function contained in this menu are: LQ, LU, QR,SCHUR, SVD, SVL.
