fipref Object Properties

Display, Data Type Override, and Logging Properties

The following properties of fipref objects are always writable:

  • FimathDisplay — Display options for the local fimath attributes of a fi object

  • DataTypeOverride — Data type override options

  • LoggingMode — Logging options for operations performed on fi objects

  • NumericTypeDisplay — Display options for the numeric type attributes of a fi object

  • NumberDisplay — Display options for the value of a fi object

These properties are described in detail in the fi Object Properties. To learn how to specify properties for fipref objects in Fixed-Point Designer™ software, refer to fipref Object Properties Setting.

fipref Object Properties Setting

Setting fipref Properties at Object Creation

You can set properties of fipref objects at the time of object creation by including properties after the arguments of the fipref constructor function. For example, to set NumberDisplay to bin and NumericTypeDisplay to short,

P = fipref('NumberDisplay', 'bin', ...
           'NumericTypeDisplay', 'short')
P =
         NumberDisplay: 'bin'
    NumericTypeDisplay: 'short'
         FimathDisplay: 'full'
           LoggingMode: 'Off'
      DataTypeOverride: 'ForceOff'

Using Direct Property Referencing with fipref

You can reference directly into a property for setting or retrieving fipref object property values using MATLAB® structure-like referencing. You do this by using a period to index into a property by name.

For example, to get the NumberDisplay of P,


ans =


To set the NumericTypeDisplay of P,

P.NumericTypeDisplay = 'full'
P =
         NumberDisplay: 'bin'
    NumericTypeDisplay: 'full'
         FimathDisplay: 'full'
           LoggingMode: 'Off'
      DataTypeOverride: 'ForceOff'
