HOMEWORK ASSIGNMENT 4
EGM 3344
Linear System Concepts
Problems from Chapra book chapters 8 through 12
For all of these problems, feel free to use a simple Matlab program to calculate function values
(like using a calculator) when the indicated approach is by hand.

8.3
Matlab
Note that the coefficient matrix is the
A
matrix.
8.4(a)
Matlab
Do not perform matrix multiplications. Just list pairs of matrices
that can be multiplied together.
8.6
Matlab
9.5
Hand
Only use Matlab for the plot.
9.6
Hand
Solve by hand, check using Matlab.
9.7
Hand
Solve by hand, check using Matlab.
9.12
Matlab
Formulate the equations by hand, solve the equations using
Matlab. Hints: Review the case study in Section 9.5 and use
central difference equations for the first and second derivative as
found on pages 101 and 103, respectively. Use
1
x
Δ=
in your
solution process. Apply the specified boundary conditions for
c
at
x
= 0 and
x
= 10 to the equations for the first and last interior
node, respectively. This is a very nice somewhat reallife
