matlab编写的声卡采集声音信号并可以播放出来的gui界面。(matlab write sound card and can play sound signals collected from the gui interface.)

关于数字图像处理中的ssda模板匹配方法。程序实现在指定图像中生成一个大小固定的矩形区域，然后用模板匹配法找出矩形位置。使用SSDA算法实现。包括源程序、待处理图像以及运行结果截图。(On digital image processing ssda template matching method. Procedures to achieve the specified image to generate a fixed size rectangular region, and then position the template matching method to find the rectangle. Using the SSDA algorithm. Including source code, pending results of the image and run shots.)

DS-CDMA中匹配滤波器误码率分析，只是一直为零，感觉没有错阿。(DS-CDMA matched filter error rate analysis, but the zero, A feeling nothing wrong.)

本程序特别适合于弹道计算等方面使用。比ODE45函数的速度加快了很多，且程序充分展示了Matlab向量运算的强大功能，以及编程的简单快捷。(This procedure is particularly suitable for use ballistic calculations and other aspects. ODE45 faster than a lot of functions and procedures for demonstrating the power of Matlab vector operations, and programming simple and quick.)
