ButterParam - Fast parameters for a digital Butterworth filter
The calculation of filter parameters with BUTTER is expensive. Therefore ButterParam stores calculated parameters in a lookup-table to accelerate repeated calls with the same input.
Example:
x = rand(10000, 1); % test data
[B, A] = butter(3, 0.6);
y = filter(B, A, x);
The relation of the processing times is: BUTTER=68% / FILTER=32%!
With [B, A] = ButterParam(3, 0.6) we get: ButterParam=14% / FILTER = 86%, and the both calls together use 35% of the version with BUTTER.
Input and output equal the BUTTER command of the Signal-Processing-Toolbox
when used with 3 inputs and 2 outputs:
[B, A] = ButterParam(N, Wn, Pass)
INPUT:
N: Order of the filter.
Wn: Cutoff frequency, scalar or [1x2].
Pass: Optional, 'low', 'high', 'bandpass', 'stop'.
OUTPUT:
B, A: Coefficients for FILTER.
