在这个更新的代码，新功能，包括colorbar，samesize包括向量plottting... ％更新版本$日期：5月18日，2011年由梁枯盎斯蒂文斯技术学院 ％更新1：更改int8到Int16的colormap的是，当电流超过64个大，这将导致错误 ％更新2：加入 samesize 为使所有的向量samesize ％更新3：添加colorbar相应的开方的幅度（ü^2+ V键^ 2） ％更新4：错误修复，当你为h = quiverc，这是行不通的。 ------------------------------------------------- ----------- (In this updated code,new features including colorbar, samesize vectors plottting are included Updated version $Date: May 18th,2011 by Liang Kuang at Stevens Institute of Tech Update 1: Change int8 to int16 when current colormap is bigger than 64,which will cause error Update 2: Added samesize for making all the vectors the samesize Update 3: Add colorbar corresponding the the magnitude of sqrt(u^2+v^2) Update 4: bug fixed,when you do h=quiverc, it doesn t work. ------------------------------------------------------------)

由于做FFT的能量泄露，频谱会出现误差，本程序用于FFT频谱的幅值和相位校正(As the leakage energy to do the FFT, the spectrum will be errors, the procedure used for the FFT spectrum of the amplitude and phase correction)
