QPSK modulation system with recover loops(This is a model of a QPSK modulation system for transmission over a bandpass channel with fc = 100 Hz and B = 30 Hz and AWGN at the receiver. SRRC fi lters with excess bandwidth α = 0.18 are employed. The receiver includes an NDA timing recovery loop followed by a DD phase recovery loop. The transmitter?s symbol period is T and set to a value of 100 ms. The symbol period at the receiver is Tr. The model will produce six windows: Two constellation plots and two eye diagrams (for the real part only), at the output of the matched fi lters and after the recovery loops a plot of the phase error (output of the NCO) and a plot of the fractional timing error (used in the interpolator). The frequency off set at the receiver is denoted by deltaf. The model simulates the transmission of 8000 QPSK symbols.)

简单易学，上手快，动手实践效果更有效，通俗易懂。(simple ，easy to use )

本文件利用matlab实现dijistra算法。主要方法是标记未走完的点，然后动态优化穷举法。(This document uses MATLAB to achieve dijistra algorithm. The main method is to mark the incomplete points, and then dynamically optimize the exhaustive method.)

sar成像最后如果要查看结果，就是这个程序实现的功能，画出峰值旁瓣比！(sar imaging Finally if you want to see the results, is the function of this program, draw peak sidelobe ratio!)

基于逻辑回归的多分类问题，可以实现至少三类数据的分类(Classification based on multiple logistic regression, classification can be achieved at least three types of data)

MATLAB 使用教程 非常简单易懂(MATLAB tutorial is very simple and straightforward to use)

该程序为matlab环境下程序，主要演示用中位点法生成分形曲面，通过三角形的不断被子分而整个表面弄成皱折，产生类似于山脉的形状——分形山。(The program for the matlab environment procedures, the main demonstration site used in the composition of the Law of Health-shaped surface, through the continuous triangle quilt divide and the entire surface of face wrinkles, resulting in similar to the shape of mountains- Fractal Hill.)
