code for contrast stretching in matlab

Improve a picture based on local mean with stdandard deviaton algorithm. No image processing toolbox is needed!

把可视化软禁啊amira中的.am格式的文件导入到matlab中 以便后续处理(Put under house arrest ah file amira visualization of .am format for import into matlab in subsequent processing)

电力系统三机九节点仿真，用于检测发电机的相电流、相电压、功率角等工作状态(Power system simulation in1 nine nodes, used to detect the generator phase current and phase voltage and power Angle working condition)

包括灰级窗和直方图，中值滤波。灰级窗成功的显示需要的切片，直方图采用多种方法来实现对一幅图片的灰度化。(Including the gray-level histogram windows and median filtering. Gray level display window successful sliced need histogram using a variety of methods to achieve a picture of grayscale.)

说明：  this source code in matlab include three parts. It help to simulate ber in mc-cdma systems

PID控制是工业工程中经常应用的方法，也比较成熟，本例中给出了伺服PID控制的私募林肯仿真(PID control is often applied in industrial engineering, is more mature, in this case gives the servo PID control of the private Lincoln simulation)

Interface that defines the methods which are common between

OFDM的matlab仿真 在学校里面做仿真实验的时候做的相关例程(OFDM matlab in school)

本程序利用MATLAB仿真在不知道信道状态信息的情况下，利用差分编码和差分接收计算误码率的程序(MATLAB simulation of the procedures used in the does not know the channel state information of the case, the use of differential encoding and differential receiver bit error rate calculation process)
