Question

Question 4 Consider the following set of equations 50.5Kg-7x2 4x2 + 7x3 + 30-0 -7x3 . 40-3x2 + 5x1 Write the given set of equations in matrix form. Use Matlab to solve for the unknowns in the equations (Round answers to four decimal places). When uploading to Blackboard, attach the script (.m) file and the variable values. e Matlab to compute the transpose of the coefficient matrix and the inverse of Afterwards, us the coefficient matrix (Round the elements of the inverse to four decimal places)

Explanation / Answer

Solution:

To solve the equation:

code:

A = [0 -7 5; 0 4 7 ; -4 3 -7];
b = [50; -30; 40];
x = A

Output:

x =

-15.1812
-7.2464
-0.1449

Transpose of matrix:

code:

A = [0 -7 5; 0 4 7 ; -4 3 -7];
AT = A'

Output:

>> matSolve1

AT =

0 0 -4
-7 4 3
5 7 -7
