这是一个matlab图像变换程序包，包括傅里叶变换、离散余弦变换、Radon变换等(This is an image transform matlab package, including Fourier transform, discrete cosine transform, Radon transform)

这是一些MATLAB图形用户设计界面的源程序，对初学着有帮助哦！(which is a MATLAB graphical user interface design of the source of a novice to help!)

ofdm发送端和接收端，根据短训练字的特性进行相关运算，进行信号到达检测，当检测到相关值大于门限一定次数后，认为有信号到达。(ofdm sending end and receiving end, according to the characteristics of the short training word correlation operation, the signal reaching the detector, when the detected correlation value is greater than the threshold after a certain number of times that a signal arrives.)

灰色系统理论是研究解决灰色系统分析、建模、 预测、决策和控制的理论.灰色预测是对灰色系统 所做的预测.目前常用的一些预测方法（如回归分 析等），需要较大的样本.若样本较小，常造成较 大误差，使预测目标失效.灰色预测模型所需建模 信息少，运算方便，建模精度高，在各种预测领 域都有着广泛的应用，是处理小样本预测问题的 有效工具(Grey system theory is the research and solution of grey system analysis, modeling, The theory of prediction, decision - making and control At present, some commonly used prediction methods (such as regression score) If the sample size is small, it often results in a comparison Large error, so that the prediction of the target failure Less information, convenient operation, high modeling accuracy, in a variety of prediction collar Fields are widely used to deal with small sample prediction problems Effective tool)

很不错的关于计算分形维的matlab代码(Very good on the calculation of the fractal dimension of the matlab code)

A股市场WIND数据库技术指标日时间序列矩阵导出(Export Database technical indicators day time series matrix A-share market WIND)

MATLAB程序，用以实现2PSK数字信号的产生(MATLAB program to achieve generation of 2PSK digital signal)

步进频信号处理模型，从信号产生到信号处理过程，到输出(step frequency)

自己写的两种susan边缘检测算子。能够较好的实现弱边缘的精确检测。(Susan wrote their own edge detection operator. Better able to accurately detect the weak edge.)
