annotate toolboxes/AudioInpaintingToolbox/Utils/evaluation/SNR.m @ 195:d50f5bdbe14c luisf_dev

- Added SMALL_DL_test: simple DL showcase
- Added dico_decorr_symmetric: improved version of INK-SVD decorrelation step
- Debugged SMALL_learn, SMALLBoxInit and SMALL_two_step_DL

function snr = SNR(xRef,xEst)
% Signal-to-noise Ratio
%
% Usage: snr = SNR(xRef,xEst)
%
%
% Inputs:
%          - xRef - reference signal
%          - xEst - estimate signal
%
% Outputs:
%          - snr - SNR
