说明：  用MATLAB实现计量经济学的教程，很完整很全面。(Using MATLAB to achieve econometrics tutorial, very complete and comprehensive.)

This code uses MATLAB s Internal Functions and Memory Preallocations to apply a Fast Implementation of kmeans algorithm. This is a efficient code for clustering a gray or Color image or it can be used for clustering a Multidimensional Array. Comparison. 1. Faster than MATLAB s internal kmeans function. 2. Consistant Output than internal kmeans. 3. 100 convergence.

永磁同步电机的直接转矩控制 可以学习S函数的编写 PID可以调节 想要的直接拿去(Direct torque control of permanent magnet synchronous motor can learn the writing of the S function of PID can adjust to take it directly)

matlab编写的正弦波的fft变换 需要的朋友可以下(matlab sinusoidal prepared the fft transform needs friends can under)

用两种向量化和一种循环的思路计算水仙花数，并给出所需时间比较 水仙花数是指一个三位数,其各个数的立方和等于该数(Quantified in two and a loop to the idea of calculating the number of daffodils and narcissus are given the time required for comparison is a three-digit number, the individual cubes, and equal to the number of)

ADSL经典仿真程序，开发环境为matlab (ADSL classical simulation program, the development environment for Matlab)
