The zip file contains matlab files for fingerprint based gender classification based on different features extracted from fingerprints.please go through the readme file.

主要是关于高等数值分析中关于CG法，MINRES法，Lanczos方法解大型稀疏矩阵的matlab算法实现(the matlab code about the advacned value analysis curriculum the algorithm for CG MINRES and Lanczos)

关于MATLAB方面的教程主要是关于如何应用等基本操作(About MATLAB aspects tutorial is about how to apply the basic operations)

对HARQ系统的吞吐量分析，模式识别中的bayes判别分析算法，粒子图像分割及匹配均为自行编制的子例程，给出接收信号眼图及系统仿真误码率，BP神经网络用于函数拟合与模式识别，用于信号特征提取、信号消噪，合成孔径雷达（SAR)目标成像仿真，有CDF三角函数曲线/三维曲线图。( HARQ throughput analysis of the system, Pattern Recognition bayes discriminant analysis algorithm, Particle image segmentation and matching subroutines themselves are prepared, The received signal is given eye and BER simulation systems, BP neural network function fitting and pattern recognition, For feature extraction, signal de-noising, Synthetic Aperture Radar (SAR) imaging simulation target, There CDF trigonometric curve/3D graphs.)

1.了解离散傅立叶变换及离散余弦变换的基本原理； 2.掌握进行FFT及逆变换的方法； 3.了解图像在频域中处理方法，应用MATLAB语言作简单的低通滤波器。 (1. Understand the discrete Fourier transform and discrete cosine transform the basic principle; 2. master for FFT and inverse transform; 3. understanding of image processing in the frequency domain method, MATLAB language for simple low-pass filter.)

Inverse discrete cosine transform of an image

Solves the mixed integer nonlinear problem:

word里包含matlab程序代码与处理效果，从原理上实现了图像的边缘检测，效果理想(matlab code word contains the treatment effect, to achieve image edge detection in principle, the desired effect)
