CS/MATH 3414 Assignment #7

1. (10 points) Exercise 6.4.4 (both parts) from your textbook.
   
   
2. (15 points) Write a function in MATLAB to determine the inverse of a given square matrix A. Your function should use the Gaussian elimination technique and the backsubstitution technique and should be written to work for any square matrix, not a matrix of a particular size. Then, using this function find the inverse of the matrix described in Computer Problem 6.4.8 (page 304) of your textbook. Compare your answer with the built-in MATLAB function inv and report your observations. Also attach a printout of your code.
   
   
3. (25 points) Computer problem 6.5.2 from your textbook. You are expected to do the coding in MATLAB. For full credit, attach printouts of your code, the results you get, and a list of observations.
