Question
Problem 5: Perform the following exercises. a) Create a 5 x 5 matrix p5a with a value of 0 for every element b) Copy the matrix in part a into a new matrix p5b. Modify the matrix p5b such that all elements on the second column have a value of 1. c) Transpose the matrix in part (b) and put the answer in p5c d) Rotate the matrix in part (b) 90 counterclockwise 3 times and put the answer in p5d. e) Are the matrices in part (c) and (d) the same? Put the answer in p5e. Do not use function isequal for this problem Problem 6: Explore different ways to solve a linear system of equations by typing help inv and help in command window, and then perform the following exercises. a) Create a 3 x 3 matrix A with the following values and set p6a=A. 1 5 6 A 8 34 7 2 9 b) Create a 3-element column vector b with values of 7.2 and 5. Set p6b=b. c) Using operator, solve the system of equations Ax=b for x. Set p6x. d) Using function inv, solve the systern of equations Ax=b for x. Set p6d=x. e) Is the answer in part (c) and part (d) the same? Put the answer in p6e. Hint: Check by setting te eual. f) Compute the difference between part (c) and (d) and put the answer in p6f.Explanation / Answer
