unitquantizer - Constructor for unitquantizer object

Syntax

q = unitquantizer(...)

Description

q = unitquantizer(...) constructs a unitquantizer object, which is the same as a quantizer object in all respects except that its quantize method quantizes numbers within eps(q) of +1 to exactly +1.

See quantizer for parameters.

Examples

In this example, a vector x is quantized by a unitquantizer object u .

u = unitquantizer([4 3]);
x = (0.8:.1:1.2)';
y = quantize(u,x);
z = [x y]
e = eps(u)

This quantization outputs an array containing the original values of x and the values of x that were quantized by the unitquantizer object u. The output also includes e, the value of eps(u).

z =

    0.8000    0.7500
    0.9000    1.0000
    1.0000    1.0000
    1.1000    1.0000
    1.2000    1.0000


e =

    0.1250
