高斯噪声随机变量发生器，这些随机变量有一个零均值，方差D。(Gaussian random variable generator，These random variables have a zero mean and variance D.)

通过对高通滤波器的理解，通过matlab编程，实现了窗函数法高通滤波器滤波(Through the high-pass filter to understand, through matlab programming, achieve a high-pass filter window function filtering)

这是关于MATLAB用于飞机图像识别所提取的特征向量，很有用处，希望对大家有用(This is about MATLAB for aircraft image recognition extracted the eigenvector, very useful, hope for everyone useful)

循环谱估计，能画出２维图，也能在某特定循环频率下画出１维图(Cyclic spectrum estimation, can draw 2 d figure, also can draw slices under a cyclic frequency)

Numerical Computing with MATLAB （by Cleve Moler) is a textbook for an introductory course in numerical methods, Matlab, and technical computing. The emphasis is on in- formed use of mathematical software. We want you learn enough about the mathe- matical functions in Matlab that you will be able to use them correctly, appreciate their limitations, and modify them when necessary to suit your own needs. The topics include * introduction to Matlab, * linear equations, * interpolation, * zero and roots, * least squares, * quadrature, * ordinary di?erential equations, * random numbers, * Fourier analysis, * eigenvalues and singular values, * partial di?erential equations.(Numerical Computing with MATLAB (by Cleve Moler) is a textbook for an introductory coursein numerical methods, Matlab, and technical computing.
