ENG 6, Spring 2016 Lab 5 Linear Algebra
Problem 1
1) Create a function, name it Lab5.m
The input of the function should be (A, B), where A is a 2-by-2 matrix, and B is a two-
element column vector.
The output of the function is X
The function should satisfy the below requirements:
Imagine
a b
A
c d
, and
e
B
f
The function should solve the system of equations
bx ay e
dx cy f
If there is no solution, or there are multiple solutions, the function returns
X=empty array (i.e. X=[]), and display “cannot solve”
If there is only one solution, the function returns the solution by a column vector
X where
x
X
y
NOTE: any other invalid input (such as giving A as 3-by-3 matrix) will be avoided during
test, so don’t worry about the invalid input.
2) Test your function
Write a script, let:
A1 = [3 1; 1 6]; B1 = [9; 20];
A2 = [3 1; 6 2]; B2 = [9; 18];
A3 = [3 1; 6 2]; B3 = [9; 20];
Call your function using Lab5(A1, B1), Lab5(A2, B2), Lab5(A3, B3), respectively.
Display the calculated result.
Submit three files:
The function file
The script file
PDF file published from the script
