网友上传的SVM的matlab程序，对初学SVM的人很有帮助(SVM Matlab程序)

五对角线性方程组的追赶法求解，同样适用于三对角(Five diagonal equations to catch up method to solve)

这段程序是关于图像区域处理的，很全面，值得一看(This process is handled on the image area, it is comprehensive, worth a visit)

飞机大角度攻击的模型仿真程序，描述了在大角度攻击时的姿态控制参数的计算。(Model for large angle of attack aircraft simulation program, described the attack in the large angle attitude control parameter calculation.)

本程序是希尔伯特黄变换中的EMD分解得到IMF分量的源程序(This procedure is the Hilbert-Huang transform EMD decomposition IMF component of the source)

搭建SISO收发系统，BPSK调制与解调，在白高斯信道下仿真系统BER性能。(Build SISO transceiver system, BPSK modulation and demodulation, the white Gaussian channel simulation system BER performance.)

将一个512×512的lena.bmp图像进行DCT变换，对得到的DCT系数按8×8块进行分层（分三层），重组填充得到新的系数矩阵，结果发现原图像的能量集中在了新图像的左上角低频部分。(The lena.bmp an image of 512 × 512 is subjected to DCT transform, the DCT coefficients obtained by layering 8 × 8 block (of three), to obtain a new recombinant filling coefficient matrix, the energy of the original image is found concentrated in upper left corner of the low-frequency part of the new image.)

该程序是一个振荡相位噪声模型。相位噪声是衡量频率标准源(高稳晶振、原子频标等)频稳质量的重要指标，随着频标源性能的不断改善，相应噪声量值越来越小，因而对相位噪声谱的测量要求也越来越高。(The program is a model of phase noise oscillator. Phase noise is a measure of frequency standard source (high stability crystal oscillator, atomic frequency standard, etc.) an important indicator of the quality of the frequency stability, with the frequency standard source performance continues to improve, the corresponding noise value smaller, and thus the phase noise spectrum of the measurement requirements higher and higher.)
