Matlab files for linear ODEs for ECE334
Ian Dobson, September 1995

This directory contains matlab M-files
to solve linear differential equations with two variables
and plot the vector fields.
The objective is to provide some computing aids
for ECE416 students to supplement their  
understanding of linear differential equations.

The files needed in the directory are
README
initialize.m
vectorfield.m
trajectory.m
timehistory.m
linearf.m

The commands are 
initialize
vectorfield
trajectory
timehistory

initialize must be run first.

The vector field can be modified 
by changing the 2 by 2 matrix A.
The initial condition can be modified 
by changing the 2 dimensional column vector x0.
Many other parameters can be changed;
print the file initialize.m to see the other parameters.

The matlab command for clearing the plot is clf.

This package is not sophisticated and 
users should improve the files to suit themselves.
Please send comments, problems or improved versions to Ian
at dobson@engr.wisc.edu.
Please let me know whether these matlab files are useful for learning
the course material.
