近似熵m文件 保证正确运行 绝不骗人(ApEn m file to ensure correct operation will not lie)

Input data is the MS Excel file, where the table of nodes, table of elements, nodal external loads vector and boundary conditions are stored. After running the mabs2d.m file on the Command Window, the program calculates the stiffness matrix in local coordinates kiL (element i). Once the transformation matrix associated to the element is obtained, the stiffness matrix in global coordinates kiG is also calculated. The table of connectivity is automatically generated for the assembly process and then computes the complete stiffness matrix of the structure.

测量控制网平差作业,在matlab下运行。(Measurement control network adjustment operations)

随机子空间法用于模态参数识别 能够识别频率阻尼(Stochastic subspace method for modal parameter identification )

学习MATLAB的参考资料，对于初学者，可以参考里面的讲解实例。(Learning MATLAB reference, for beginners, can explain the instance reference inside.)

This document have matlab code for sine wave and inverse descrete fourier transform and to generate noise signal

说明：  自己写的isodata聚类程序，已经在matlab下调试验证通过。(Wrote it myself ISODATA clustering procedure has been adopted to verify matlab debugging.)

说明：  这个模型可以在MATLAB中计算资金的贬值情况，根据利率与时间的长度，最后得到资金的现值或终值( For example, the cost of an asset is $13,000 with a life of 10 years. The salvage value of the asset is $1000. To find the remaining depreciable value after 6 years, use the following commands. Find the accumulated depreciation with the straight-line depreciation function, DEPSTLN. )
