Question

Suppose that x = [10, -2, 6, 5, -3] and y = [9, -3, 2, 5, -1]. Find the results of the following operations by hand and use MATLAB to check your results.

a. z = (x < 6)

b. z = (x <= y)

c. z = (x == y)

d. z = (x ~= y)

Answer 1

(a)

z = (x<6)
z = 0 1 0 1 1

(b)

z = (x<=y)
z = 0 0 0 1 1

(c)

z = (x==y)
z = 0 0 0 1 0

(d)

z = (x ~ =y)
z = 1 1 1 0 1

 

MATLAB CODE:

%Code start

clear all

x = [10 -2 6 5 -3];
y = [9 -3 2 5 -1];

z = x < 6
z = x <= y
z = x == y
z = x ~= y

%Code end

 

Code run result:

z = 0 1 0 1 1

z = 0 0 0 1 1

z = 0 0 0 1 0

z = 1 1 1 0 1

 

The results from hand and result from MATLAB are matching.

a)

z = (x<6)
z = 0 1 0 1 1

(b)

z = (x<=y)
z = 0 0 0 1 1
