decomp_reconst_WU
Decompose image into subbands (undecimated wavelet), denoise, and recompose again.
fh = decomp_reconst_wavelet(im,Nsc,daub_order,block,noise,parent,covariance,optim,sig)
im : image
Nsc: Number of scales
daub_order: Order of the daubechie fucntion used (must be even).
block: size of neighborhood within each undecimated subband.
noise: image having the same autocorrelation as the noise (e.g., a delta, for white noise)
parent: are we including the coefficient at the central location at the next coarser scale?
covariance: are we considering covariance or just variance?
optim: for choosing between BLS-GSM (optim = 1) and MAP-GSM (optim = 0)
sig: standard deviation (scalar for uniform noise or matrix for spatially varying noise)

gold_sequence
Gold序列因为其良好的伪噪声特性，经常作为CDMA扩频系统仿真中的用户扩频序列，用MATLAB可以产生各种长度的Gold序列优选对，在此基础上，产生混沌序列等其他性质的扩频序列也很容易。(MATLAB script for Illustrative Gold sequence generation)
