Implement a nonuniform quantizer as the following piecewise function:
y = -3.5, x < -3
y = -1.5, -3 ≤ x < -1
y = -0.5, -1 ≤ x < 0
y = 0.5, 0 ≤ x < 1
y = 1.5, 1 ≤ x < 3
y = 3.5, 3 ≤ x
Your function should act elementwise on array inputs.
For example:
nonuniformQuantizer([-4.0 0.0 2.0])
returns
[-3.5 0.5 1.5]

I think the first line should read x<-3, not x<3.
Fixed. Thanks.
