Question
Q1 (3) e) Use MATLAB commands to enter the matrices and the commands to solve the
following system:
10x + 2y
z = 27
- 3x - 6y +2z = -61.5
x + y + 5z = -21.5
Save all entered data, the commands, and the results; and submit in separate file or with the file
other questions.
Q2
Given the vector A = [1, 1.5, 2, 2.5,..., 20] and the vector B= [-20, -19.5, -19, -18.5,..,. -1]
Write a program in MATLAB, using the editor, to find the sum of 2A+B. Write the function, enter the
data, and invoke the function to find the results.
Save all entered data, the commands, the program and the results; and submit in a separate file or
with the file of other questions.
Q3(? ; Given that cos(x) and sin(y) are defined on the interval [-21, 2π], with increment 0.2 in
each of x and y. Write the commands in MATLAB to draw the surface of
z = (5cos(x))² + (5sin ) 2
Save all the entered data, the commands, and the graph of the surface; and submit in a separate
file or with the file of other questions.
