模拟退火算法在飞机巡航中的应用，采用MATLAB编写。(Simulated annealing algorithm in aircraft cruise, using MATLAB prepared.)

这是基于MATLAB的回声状态网络，可用于趋势测量(This is based on MATLAB echo state network that can be used to measure trends)

关于演示旋转的一个应用程序，可以更好的理解体旋转的过程(The project is made by using GUIDE of Matlab 7.5.0 (R2007b) and user-defined classes. The project may be used on the seminars on mechanics in the technical educational establishments. Rigid body section of a course of mechanics is considered as required in most technical colleges and Universities. Sometimes it s difficult to imagine a rotation of a rigid body in the three-dimensional space. Especially, when an asymmetric top is in question. Rigid Body project may help students to see the rotations clearly as though they were in the real world. Author of Rigid Body project: Ferat Talat oglu )

Matlab中的fsolve函数源代码。可用于解方程。(Matlab fsolve function of the source code )

MATLAB的gui指导，各种情况详细的代码(MATLAB-gui guide, the code in detail the various situations)

这个模型模拟配置的GSM运营定点数字下变频器（DDC），利用Simulink，DSP模块，以及定点模块组。该模型模拟了TI/ GrayChip GC4016四路数字下变频芯片一种操作方式(This model simulates a fixed-point Digital Down Converter (DDC) configured for GSM operation, using Simulink, DSP Blockset, and the Fixed Point Blockset. The model emulates one mode of operation of the TI/GrayChip GC4016 Quad Digital Down Converter chip)

本程序仿真了AWGN信道下，采用DS扩频对bpsk信号的影响，扩频码采用walsh码，扩频因子16； 接收端进行rake接收，然后分集合并，比较了三种分集方式对误码率的影响 从图像可以看出在扩频因子较高的情况下，最大比值合并与等增益合并性能相近(This program simulates the AWGN channel, using DS spread spectrum signal for bpsk influence spreading code using walsh code spreading factor 16 Rake receiver receiving end, and diversity combining, diversity compares three methods on the bit error rate of As can be seen from the image in the case of higher spreading factor, the maximum ratio combining and equal gain combining similar performance)

点目标成像程序，程序简洁，效果较好，具有一定的使用价值(ISAR image)

归一化后截止频率为0.2的数字低通滤波器，并且能有效滤掉工频干扰，使心电信号有效表达信息。(The normalized digital low-pass filter with a cutoff frequency of 0.2, and can effectively filter out power frequency interference, so that the ECG signal can effectively express information.)

说明：  尝试自定义卷积函数，包含功能测试实现代码。(Custom convolution function and test implementation)
