%
% Peter L. Soendergaard, 2007 - 2018.
%
% General
% RMS - Root Mean Square norm of signal.
% NORMALIZE - Normalize signal by specified norm.
% GAINDB - Scale input signal
% CRESTFACTOR - Compute the crest factor of a signal.
% UQUANT - Simulate uniform quantization.
%
% Window functions
% FIRWIN - FIR windows (Hanning,Hamming,Blackman,...).
% FIRKAISER - FIR Kaiser-Bessel window.
% FIR2LONG - Extend FIR window to LONG window.
% LONG2FIR - Cut LONG window to FIR window.
% FREQWIN - Freq responses (Gauss,Gammatone,Butterworth,...)
%
% Filtering
% FIRFILTER - Construct an FIR filter.
% BLFILTER - Construct a band-limited filter.
% WARPEDBLFILTER - Warped, band-limited filter.
% FREQFILTER - Construct a full length frequency side filter.
% PFILT - Apply filter with periodic boundary conditions.
% MAGRESP - Magnitude response plot.
% TRANSFERFUNCTION - Compute the transfer function of a filter.
% PGRPDELAY - Periodic Group Delay
%
% Ramping
% RAMPUP - Rising ramp.
% RAMPDOWN - Falling ramp.
% RAMPSIGNAL - Ramp a signal.
%
% Thresholding methods
% THRESH - Coefficient thresholding.
% LARGESTR - Keep largest ratio of coefficients.
% LARGESTN - Keep N largest coefficients.
% DYNLIMIT - Limit the dynamical range.
% GROUPTHRESH - Group thresholding.
%
% Image processing
% RGB2JPEG - Convert RGB values to the JPEG colour model
% JPEG2RGB - Convert values from the JPEG colour model to RGB
%
% Tools for OFDM
