基于MATLAB开发环境下的短时傅立叶变换的工具箱(MATLAB development environment based on short-time Fourier transform Toolbox)

说明：  我使用matlab寫的漸層處理程式，希望初學者可以進快上手。(I use matlab gradient processing program to write and hope into the beginners get started quickly.)

这个程序可用来画R(D)函数，学习信息论的一般要做这个。(This procedure can be used to draw R (D) function, learning the general information theory to do this.)

用信号发生器产生的信号，用屏幕录像专家录的声音，用频谱分析仪打开做时域频域分析时可以很好的检测出来(Signal with a signal generator, with the voice recording screen video experts, open to do with the spectrum analyzer frequency domain analysis of time-domain can be detected well)

Hi to all. This is a user guide doc. enjoy it

说明：  结合李银斌同学的论文第三章，得到NUFFT算法。zl为非均匀采样值，xl为非均匀网格点，ul为与xl最近的均匀网格点。得到的zk为，均匀频谱(Non-uniform fast Fourier transform)

图像的方向图处理，通过各类算法实现方向图的获取。(The direction of image processing, algorithm through various access patterns.)
