Que.What would be the output of the following code (in editor window)?
X = [1.4+2.3i 3.1-2.2i -5.3+10.9i]
X = 1.4000 + 2.3000i   3.1000 - 2.2000i  -5.3000 +10.9000i
Y = fix(X)

a. Y = 1.0000 + 2.0000i 3.0000 – 4.0000i -5.0000 +10.0000i
b. Y = 2.0000 + 3.0000i 3.1000 – 2.2000i -5.3000 +10.9000i
c. Y = 1.0000 + 2.0000i 3.0000 – 2.0000i -5.0000 +10.0000i
d. Y = 2.0000 + 3.0000i 3.1000 – 2.2000i -5.3000 +10.9000i
