PID_3

本程序是建立了三维椭球随机分布模型，并绘制出分布图像。(This procedure is to establish a three-dimensional ellipsoid model of random distribution, and to map out the distribution of the image.)

《精通matlab7.0混合编程》的例子程序，其中涉及MATLAB程序和VC++程序，其中大部分为改书所附光盘。()

Linear prediction follows naturally from the general mathematics of linear systems. As the system output is defined as a linear combination of past samples, the system’s future output can be predicted if the scaling coefficients bj and ak are known.

说明：  一个用MATLAB实现的单位转换程序，包括质量单位转换和长度单位转换。(MATLAB realization of a unit with the conversion process, including quality and length of unit conversion unit conversion.)

LLE算法基于swiss roll与s-curve数据集的运行结果，选取的样本点数为N=2000、k=12、 d=2进行的降维运算的结果,由运算结果可知在不同的数据集上LLE算法依然能够很好地保持数据在降维前后结构的特点。(The LLE algorithm is based on the running results of Swiss Roll and S-curve data sets, and the number of selected sample points is the result of dimensionality reduction of N=2000, k=12 and d=2. It is known that LLE algorithm still can maintain the characteristics of the data before and after dimensionality reduction well on different data sets.)
