    Finally, we now mention MATLAB commands that can be used to help in the partial fraction decomposition of rational functions. This can be used when we need to express the Laplace transform as a partial fraction and then using a table and uniqueness property of the Laplace transform derive the time function. First, lookup how the commands collect and expand work. Now, read up on the documentation of command [x,p,k]=residue (b, a) to answer the following questions. Lab Exercise 1....
