Two changes to the Maxima by Example Series:

======================================

The new Ch. 5 of Maxima by Example includes a

discussion of generalized eigenvectors, Jordan

chains, canonical bases, Jordan canonical form,

construction of the inverse of a matrix by row operations,

and four analytic methods of calculating the exponential

matrix exp(t*A). The software file mbe.mac contains

many tools to study matrix methods and properties.

Chapter 5: Matrix Solution Methods

Chapter 5 shows the use of Maxima matrices

for the solution of eigenvalue and eigenvector problems,

and the analytic matrix solution of sets of first order

ordinary differential equation initial value problems.

Maxima 5.36.1

============================================

The old Ch. 5 on the qdraw interface to draw2d has been

moved to Ch. 13 of Maxima by Example, and contains

new examples including drawing a density plot directly

from a matrix of numerical values, drawing a scatterplot

(with a linear fit) of the wait times vs. eruption
durations

for the Old Faithful Geyser. Also added are more examples

of using Greek letters, mathematical symbols and adjustable
font.

Chapter 13: 2D Plots and Graphics using qdraw

Chapter 13 presents many examples which use qdraw.mac, an

interface to Maxima's draw2d function. qdraw(...) provides much

quicker access to many features of draw2d, with default plot

properties of interest to users from the physical sciences and

engineering. This chapter is the old chapter 5.
