lorez关联维数是混沌时间序列的很重要的性能指标(lorez correlation dimension of chaotic time series is a very important performance index)

说明：  hough变换，可以经过图像的边缘点实现霍夫变换，即实现空间转换！(hough transform, image edge points can be achieved through the Hough transform, that is to achieve space conversion!)

PCA算法的matlab程序。本代码是对一维信号进行PCA降维处理的matlab函数。(PCA algorithm matlab program. This code is a one-dimensional signal processing PCA dimensionality reduction matlab function.)

Pitch Determination Algorithm(Extract pitch of speech signal based on subharmonic-to-harmonic ratio)

说明：  流形自适应学习算法，能时间在Matlab上运行，并包含参考文献。(the program running on the Matlab platform.)

forster特征点检测的matlab实现(forster feature point detection in matlab implementation)

BP 神经网络算例，很好的算例程序，希望对大家有帮助(BP neural network example, the example program, we hope to help)

频域内的模态参数识别方法之多参考点最小二乘复频域法，完全自己编写，希望有同样做模态参数识别的前辈给予指教与帮助(Frequency domain modal parameter identification methods as much as the reference point complex frequency domain least-squares method, completely on my own to write, want to have to do the same modal parameter identification predecessors give advice and help)

关于普朗克分布的详细讨论。（在mathematica环境下开发）(A detailed discussion of Planck distribution )

神经计算，本代码主要介绍BP神经算法的主要步骤，非常简单有很明了，非常适合阅读 (Neural computing, the main source of the main steps of BP algorithm is very simple, very clear, very suitable for reading)
