证券及期货条例： Submodular 函数优化工具箱

颜色处理类matlab工具箱，支持图像色度、亮度编辑，颜色分段等(Deal with category colors matlab toolbox to support the image chroma, brightness edit, and so the color sub-)

主要用于建模校正集和预测集样品的选择。近红外光谱模型(Mainly used for modeling calibration set and prediction set of samples to choose from.)

该函数用于读取ecg信号，找到小波变换模极大序列.(This function is used to read the ecg signal, find the sequence of wavelet transform modulus maxima.)

OFDM 的一些 Matlab仿真程序 适合初学者学习借鉴(OFDM some Matlab simulation program for beginners to learn from)

系统辨识在控制领域具有广泛的应用。一个系统在进行设计和控制前，要得到系统的模型，通常对于较为复杂的系统，我们选择用系统辨识的方法得到系统模型。最小二乘法是系统辨识中常用的且很有效的一种方法，利用误差平方最小化的原理，实现估计系统模型与实际系统模型的最佳拟合。

基于LSB的直接4bit替换法，就是直接用秘密图像像素值的高4bit去替换载体图像像素值的低4bit。 (Direct 4bit substitution, that is, the direct use of the secret image pixel values of the high-4bit image pixel value to replace the carrier' s low 4bit.)

可以提取一幅图中想要的目标，多抽样率信号处理，计算多重分形非趋势波动分析。( Target can be extracted in a picture you want, Multirate signal processing, Calculate the multifractal trend fluctuation analysis.)

说明：  对指定的一幅含有多个目标的灰度图像，进行基于阈值的图像分割处理，对结果图像进行基于数学形态学的后处理设计，以得到更理想的目标区域。最后对结果图像进行区域标记（以颜色区分不同区域）并提取目标个数、各目标区域的面积、圆形度等特征。(The gray image with multiple targets is segmented based on threshold, and the result image is designed based on mathematical morphology to get a better target area. Finally, we mark the region of the result image (distinguish different regions by color) and extract the number of targets, the area of each target region, roundness and other features.)

自己用支持向量机编的一个小程序，很好的实现了分类(Their series with support vector machine is a small program achieved very good classification)

单载波频域均衡，用来恢复信号的，使传输信号的失真最小。(Single-carrier frequency domain equalization is used to restore the signal to transmit the minimum signal distortion.)
