matlab function 图像增强 1. 直方图均衡化的 Matlab 实现 1.1 imhist 函数 功能：计算和显示图像的色彩直方图 格式：imhist(I,n) imhist(X,map)(matlab function)

This is a simple, yet useful Bloch equation simulator that runs in Matlab. It is written as a MEX function so that it can run reasonably quickly, and simulate RF and a 1D gradient waveform. Simulations can be run for a range of spatial offsets and frequency offsets.

模拟信号的数字化传输---增量调制系统 用SIMULINK建立简单增量调制系统的模型并进行 （3） 正弦信号 （4） 语音信号 的传输。 改变抽样频率和量化台阶大小，观察重建信号以及量化噪声信号的波形；对于语音信号主观评价声音质量的变化。 (Digitized analog signal transmission systems--- delta modulation delta modulation SIMULINK easy set up of the model system and (3) sinusoidal signal (4) transmission of voice signals. Change the sampling frequency and quantization step size, to observe the reconstruction of signal and quantization noise signal waveform for subjective evaluation of the speech signal changes in sound quality.)

一个讲述MATLAB基础的ppt格式的教程，内容比较详尽(About the basis of a MATLAB tutorial ppt format, content, more detailed)

一本很好的matlab零起点学习手册，通过该手册可以逐步掌握matlab的编程方法(A very good learning manual matlab beginners, step by step through the manual to master the programming method matlab)

a useful c++ pdf for beginners, the document contains examples and tips and also a simple explanation.

生成正弦波，不需要调用sin函数，利用的查表法(Generate a sine wave, you do not need to call the sin function using table look-up method)

灰色gm(1,1)模型，当做函数可以调用，中间注释写得很详细，稍加修改即可成为灰色系统中别的算法。(Gray gm (1,1) model, as a function can call the Notes between very detailed, a little modification to the system as a gray-level algorithm.)

this is program to to add noise to an image,you have to first set path to "C:dspprojects"and copy any image(512*512) to that path...
