evaluates a linear basis function and computes L2 and H1 error for 1D finite element method

this is a code for viterbi in the forward mode

这是matlab用户手册，对于初学者很有益，里面涉及到各个方面，很有价值的参考资料。(This is a matlab user manual, very useful for beginners, which relate to various aspects valuable reference.)

Matlab code to study the decorrelation and energy packing efficiency of three transform techniques: Karhunen-Loève transform (KLT), discrete-cosine transform (DCT), and Walsh-Hadamard transform (WHT). Using a given vector of signal samples, it transforms the signal vector, quantize the transformed samples, and reconstruct the signal samples from the quantized samples

this helps for range filtering

将小波相邻系数相关性的降噪思想引入到冗余第2代小波中，提出了基于邻域相关性的冗余第2代小波降噪方法，该方法克服了传统阈值降噪没有考虑小波系数之间相关性的不足。(Aiming at fault feature extraction in the background of strong noise, a wavelet denoising idea by incorporating neighboring coefficients is introduced into redundant second generation wavelet case. A denoising method of redundant second generation wavelet using neighbor dependency is presented. It overcomes the deficiency of traditional thresholding approaches. In this method, an original signal is decomposed by redundant second generation wavelet, and the detail and approximation signals have the same length as the original signal. The detail signals at each scale are then processed by neighbor dependency. Finally, the approximation signal and processed detail signals are reconstructed by inverse transform of redundant second generation wavelet to realize the signal denoising. )
