% KSVD running file
% in this file a synthetic test of the K-SVD algorithm is performed. First
% a random dictionary with normalized columns is being generated and then
% a set of data signals each as a linear combination of 3 dictionary
% element is created with noise level of 20SNR. this set is given as input
% to the K-SVD algorithm.
% a different mode for activating the K-SVD algorithm is until a fixed
% error is reached in the Sparse coding stage instead until a fixed number of coefficients is found
% (it was used by us for the
% denoising experiments). in order to switch between those two modes just
% change the param.errorFlag (0 - for fixed number of coefficients 1 -
% until a certain error is reached).
param.L = 3; % number of elements in each linear co
