离散傅里叶变换对于FDTD计算程序很有用( an algorithm resistant to print/scan process is proposed , which is based on block discrete fourier transform)

Matlab GUI开发的简单的数字图像处理方法(Matlab GUI developed a simple method of digital image processing)

说明：  改写的matlab fft程序，能对fft结果幅度调整和对横坐标的频率实行自动匹配(Matlab fft procedure adapted to the results of the fft and the abscissa is adjusted automatically to match the frequency of)

This document will describe some of the general usage of MATLAB s Data Acquisition Toolbox (DAT). The software in the toolbox allows MATLAB to acquire data from sensors and to send out electrical signals that can be used to control or drive external devices. We will be using this toolbox with two different pieces of hardware. One is the sound card built into your laptop, the microphone and speaker will serve as the data acquisition (and output) devices. The sound card provides convenience because it will allow you to test the DAT outside of the lab. We will also be using Measurement Computing data acquisition cards that will ¯ t into your laptops PCMCIA slot, these devices will be in the class laboratory. The data acquisition (DAQ) cards allow your computer to acquire data from many different types of sensors.

单频估计kay算法的仿真源程序，系统为QPSK调制，信道为高斯白噪声信道。(Single frequency estimate kay algorithm simulation source code, the system is QPSK modulation, the channel is Gaussian white noise channel.)

This code uses MATLAB s Internal Functions and Memory Preallocations to apply a Fast Implementation of kmeans algorithm. This is a efficient code for clustering a gray or Color image or it can be used for clustering a Multidimensional Array. Comparison. 1. Faster than MATLAB s internal kmeans function. 2. Consistant Output than internal kmeans. 3. 100 convergence.
