Two class problem classification sample

有详细的注释，用平面波展开法计算二维声子晶体带隙,利用matlab针对图像进行马氏距离计算 。( There are detailed notes, Computation Method D phononic bandgap plane wave, Using matlab to calculate the Mahalanobis distance for the image.)

Dragon Forth (DF) is a powerful tool for creating applications for Palm OS of any complexity. The name Forth means fully compatibility with ANS 94 standard.

Add noise to signal at a prescribed SNR level.

说明：  通过经验模态分解emd波形分割，将脉冲波形分为多个部分，基于EMD的时频分析方法既适合于非线性、非平稳信号的分析(By empirical modal decomposition emd waveform segmentation, the pulse waveform is divided into several parts, and the time frequency analysis method based on EMD is suitable for nonlinear and non-smooth signal analysis)

国外的潮流计算程序 MATLAB矩阵思想很重要 我有些糊涂 希望大家共同讨论(Program abroad, the trend of thought is very important MATLAB matrix confused me some hope that we discuss)

求卷积及两个序列的互相关函数，或一个序列的自相关函数；(for convolution and two sequences of cross-correlation function, or a series of auto-correlation function;)

particle swarm optimization

用于求解含有状态约束以及输入约束的预测控制问题(Constraint MPC)
