MATLAB Questions. Part 3 Exercises
Recall that a= last digit of your student ID,b= second to last digit of your student ID,c= third to last digit of
your student ID, and d= the sum of the last three digits of your student ID. Complete the following operations in
your script, making new lines for each operation.
(a+1)x+(b+1)y=-9
(c+1)x+(d+1)y=-4
3A)(Solve system of linear equations, Method 1) Solve the above system of linear equations using reduced row
echelon form. In other words, declare a 23 coefficient matrix called P3AM for the system above (make a matrix
with just numbers, no variables), then use the reduced row echelon form command to solve the system. Declare
the solution in MATLAB as P3A.3B)(Solve system of linear equations, Method 2) Solve the same system of linear equations using an inverse
matrix. In other words, declare a 22 coefficient matrix called P3BM for the same system (make a matrix with
just numbers, no variables, but only for the side with the x and y on it), then declare a 21 vector called P3BV
with the numbers on the right side of the equation. If we let x=[x;y], then the system turns into (P3BM)(x)=
(P3BV); therefore, the solution to the system should be x=(P3BM)-1(P3BV). Use the proper inverse matrix
operation and declare the solution in MATLAB as P3B. Check that your results match the prior method from 3A. The work should be done by using the MATLAB.
