matlab要求编写函数，并画出图的matlab习题，供大家参考(prepared Matlab functions, and draws a plan of Matlab Exercise, for your reference! !)

直方图均衡：原始图的直方图变换为均匀分布的形式，这样就增加了象素灰度值的动态范围从而达到增强对比度的效果 中值滤波：中值滤波属于非线性平滑滤波器，它可以消除噪声又能保护图象的细节(histogram equalization : the original plan to transform the histogram in the form of uniform distribution. This will increase the value of the pixel gray areas so as to achieve dynamic contrast enhanced effect of filtering : Median filter is nonlinear smoothing filter, it can eliminate noise while preserving image details)

该源代码程序是关于张德丰所编写matlab小波分析的第五和六章(the sourcecodes are match with the book named matlab wavelet analysis by Zhang Defeng)

s变换，是当前比较流行的时频分析算法，可以用于地震数据时频分析和频谱分析，该程序基于matlab平台，实现了s变换和反变换。(s transformation, is the more popular time-frequency analysis algorithms, can be used for seismic data analysis and time-frequency spectrum analysis, the program based on matlab platform realize the s transform and inverse transform.)

reads files and an offset to the coordinates of the selected objects

1.AQMC较正的matlab源代码，适用于各种DAC及正交调制器引起的IQ不平衡较正(Than positive 1.AQMC matlab source code, suitable for all kinds caused by the DAC and quadrature modulator IQ imbalance correction)

说明：  通过拟合计算Qa，对较多的地理数据分析比较有用(By fitting the calculated Qa, geographic data analysis on more useful)

说明：  DOA估计算法,是一种有效的算法,方便,快捷(DirecTionofArrinal)

这是一个用Matlab编写的程序集，可以实现一些声音和图象的处理。声音的处理有：LPC，FFT，共振峰，频谱等。图象的处理也有很多，都有源代码和参考代码。还有非常友好的界面。(This is a Matlab prepared by the procedure set, can achieve some of the voices and image processing. Voice processing : LPC, FFT, formants and spectrum. Image processing there are many, have the source code and reference code. There are extremely friendly interface.)

利用matlab画出系统在一定参数下的分叉图，并观察得到的分叉图了解系统可能发生的变化(Using matlab draw system under certain parameter bifurcation diagram and observe the changes resulting bifurcation diagrams for the system may occur)
