quantizer Object Properties

The following properties of quantizer objects are always writable:

• DataMode — Type of arithmetic used in quantization

• Format — Data format of a quantizer object

• OverflowMode — Overflow-handling mode

• RoundMode — Rounding mode

See the Property Reference for more details about these properties, including their possible values.

For example, to create a fixed-point quantizer object with

• The Format property value set to [16,14]

• The OverflowMode property value set to 'saturate'

• The RoundMode property value set to 'ceil'

type

q = quantizer('datamode','fixed','format',[16,14],...
    'overflowmode','saturate','roundmode','ceil')

You do not have to include quantizer object property names when you set quantizer object property values.

For example, you can create quantizer object q from the previous example by typing

q = quantizer('fixed',[16,14],'saturate','ceil')

Note   You do not have to include default property values when you construct a quantizer object. In this example, you could leave out 'fixed' and 'saturate'.
