利用传统方法及MUSIC方法估计信号DOA，其中阵列为ULA(Use of traditional methods and MUSIC methods are used to estimate the signal DOA, one array for the ULA)

将矩阵中的数据输出到EXCEL表格，共四个通道~(The matrix of the data output to the EXCEL table, a total of four channels ~)

Series Resistor Inductor Circuit

说明：  该程序为文本文档，可在matlab 中运行(the procedures for text documents can be run in Matlab)

matlab有限元 3-D FDTD code with PEC boundaries (matlab finite element 3-D FDTD code with PEC boundaries)

this program finds the number of zero crossings in a given signal.

TDOA定位以及改进方法,有基础的算法，以及一些改进后的方法(TDOA location)

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)
