用matlab编程做的《有限元法基础与程序设计》第二章的例子 方法三(FEA matlab )

基于角度和时延联合估计（JADE）算法MATLAB仿真程序(Based on joint angle and delay estimation (JADE) algorithm MATLAB simulation program)

OFDM的关键技术和应用，非常非常好用的一本书(Key technologies and applications of OFDM, very, very easy to use book)

根据地震记录的统计特征和相应假设，本文采用 ARMA 模型描述地震子波，基于 高阶累积量的 ARMA 模型地震子波提取方法不仅可在压制高斯色噪声的同时保留所需 地震信号的相位信息(For the cumulant based ARMA (autoregressive moving average ) model seismic wavelet extraction method could not only retain the pahse information of the seismic wavlet while eliminating the colored Gaussian noise, but also provide a parsimonious, more efficient )

题目：有1、2、3、4个数字，能组成多少个互不相同且无重复数字的三位数？都是多少？ 1.程序分析：可填在百位、十位、个位的数字都是1、2、3、4。组成所有的排列后再去 　　　　　　掉不满足条件的排列。 (Title: There are numbers 1,2,3,4, how many can be composed of distinct three-digit numbers without repetition? Is how much? 1. Program Analysis: fill in the hundred, ten, a bit of the numbers are 1,2,3,4. Composed of all the permutations and then remove the arrangement does not meet the conditions.)
