disp

Display a quantizer, quantized FFT, or quantized filter

Description

Similar to omitting the closing semicolon from an expression on the command line, except that disp does not display the variable name. disp lists the property names and property values for a quantizer, quantized filter, or quantized FFT.

The following examples illustrate the default display for a quantized FFT F and a quantizer q.

• F = qfft;
  disp(F)
               Radix = 2
              Length = 16
   CoefficientFormat = quantizer('fixed', 'round', 'saturate', [16  15])
         InputFormat = quantizer('fixed', 'floor', 'saturate', [16  15])
        OutputFormat = quantizer('fixed', 'floor', 'saturate', [16  15])
       OperandFormat = quantizer('fixed', 'floor', 'saturate', [16  15])
       ProductFormat = quantizer('fixed', 'floor', 'saturate', [32  30])
           SumFormat = quantizer('fixed', 'floor', 'saturate', [32  30])
    NumberOfSections = 4
         ScaleValues = [1]
  
  q = quantizer
  q = 
              Mode = fixed
         RoundMode = floor
      OverflowMode = saturate
            Format = [16  15]
               Max = reset
               Min = reset
        NOverflows = 0
       NUnderflows = 0
