通过应用于小波变换到lena.jpg图像，简单实现图像压缩，实现一级压缩和二级压缩(Through applied wavelet transform to lena.jpg image, a simple image compression, compression and two compression to achieve a)

PDE solutions for convection problems

根据BS公式，通过Mente Carlo模拟对欧式期权进行定价的源码。即使不是做期权定价的，该源码也是一个非常好的理解如何做Mente Carlo模拟的实例。(Based on the Black-Scholes formula, codes for pricing the European options through the Mente Carlo simulation. It is a very good example for your understanding of how to do Mente Carlo simulation, even if you do not engage in the option pricing.)

说明：  无功功率分离谐波成分和基波成分，采用数学形态学滤波器作为低通滤波(Reactive power components of the separation of harmonic and fundamental components, the use of mathematical morphology filter as a low-pass filter)

The goal of this program is to demonstrate the construction of a huffman encoding tree. The tree is represented as a binary tree using MATLAB s built in treeplot commands. Contruction of the tree as well as the huffman code book will be described in later sections

介绍科学计算技术和mat lab相结合的书籍，很专业(Introduction to scientific computing and mat lab combination of books, very professional )

DWT is any wavelet transform for which the waveletsDaubechies wavelets are discretely sampled. The code uses

This is a basic program for quan filter for filtering multiplicative noise it gives reasonable output for speckle noise removal

液压泵振动信号的小波包分解以及功率谱分析，仿真信号的Hilbert谱以及边际谱；仿真信号的小波包能量计算(wavelet packet decomposition and power spectrum of vibration signals for piston pump Hilbert spectrum and marginal spectrum of stimulated signals)

ML法能够很好的估计信号的信噪比,DC-DC部分采用定功率单环控制，代码里有很完整的注释和解释。( ML estimation method can be a good signal to noise ratio, DC-DC power single-part set-loop control, Code, there are very complete notes and explanation.)
