基于kalman的机器人slam，可用于二维和三维！(Kalman-based robot slam, can be used for two-and three-dimensional!)

fcm code for matlab 2009 and can clustering the item into several clusters with this algorithm

MATLAB实现EMD分析振动信号时的波形匹配延拓，此方法可以一定程度上降低希尔伯特黄变换引起的端点效应(MATLAB to achieve EMD analysis of vibration signals when the waveform matching extension, this method can be reduced to some extent, the Hilbert yellow transform caused by the endpoint effect)

to understand the Algorithm go to matlab help in page dct2 and idct2 to get the mathematical expression for M = N = 8, we can calculate the most of hard values and save it as LUTs to speed up the execution now compare our special 8X8 functions with the internal general functions use this code: A = int32(100*rand(8,8)) tic for i = 1 : 1000 IDCT_8X8(DCT_8X8(A)) end toc tic for i = 1 : 1000 idct2(dct2(A)) end toc i had built the general functions too, but with low speed (to understand the Algorithm go to matlab help in page dct2 and idct2 to get the mathematical expressionfor M = N = 8, we can calculate the most of hard values and save it as LUTs to speed up the executionnow compare our special 8X8 functions with the internal general functionsuse this code: A = int32 (100* rand (8,8)) tic for i = 1: 1000 IDCT_8X8 (DCT_8X8 (A)) end toc tic for i = 1: 1000 idct2 (dct2 (A)) end toc i had built the general functions too, but with low speed)

针对多径信道的信道均衡，演示了几种经典的算法。可以直接运行。画图时是动态的，做得很精细。(Multipath channel for the channel equalization, demonstrate several classic algorithms. Can be directly run. Paint is dynamic, so very fine.)
