基于MATLAB的算法，以及其作用在数学领域的应用与研究(MATLAB-based algorithm, and its role in the field of application and research of mathematics)

说明：  可用于求解六自由度并联机器人正解的matlab程序(Matlab program that can be used to solve the forward solution of a 6-DOF parallel robot)

matlab code for finite element Q4

采用时频聚集性较好的线性调频信号作为线性时不变系统输入激励，采用Gabor字典作为过完备原子库。在利用传统系统辨识法之前先利用稀疏分解算法将输出信号进行去噪处理，显著提高系统辨识精度。 具体包括互谱算法，信号的Gabor稀疏分解的详细代码(Space can be a time for sparse decomposition to solve the problem of huge memory needed。This approach, combined with the rapid decomposition of FFT for signal ,so as to achieve satisfactory results.)
