细梁的振动，无量纲振动控制方程关于梁的动力响应(Beam power with applications from mechanical aerospace electrical and civil engineering free vibration nondimendional frequency coefficients on the dynamic behaviour of the beam)

利用Matlab计算quality factor. 输入是谐振波谱的数据，输出为：谐振频率，谐振幅度和quality factor。(Matlab coding. Calculate quality factor of resonator based on transmission spectrum data.)

压缩包包含三个文件： 全主元高斯-约当消元法程序AGJDN.m；基于全主元高斯-约当消元法的迭代求解病态矩阵方法AGJDNM.m；AGJDN.m的测试方程。 程序参考自：Fortran常用算法程序集（第二版） 徐世良编。AGJDN.m能求解部分病态矩阵，而AGJDNM.m对于我的测试矩阵效果不佳，但也一并上传，仅供参考。 错漏之处，还望指正。 (Gaussian-Jordan elimination base on all principal element.)

有关ABAQUS计算多相材料的前处理器，包括网格划分及区域划分(ABAQUS calculation of multiphase material about previous processors, including mesh and zoning)

我自己用c语言写的64点基4FFT算法，在visual c++ 6.0环境下编译通过。同matlab结果一致。(My own use C language to write the 64 based 4FFT algorithm, in visual c++ 6 compiler environment through. Results consistent with matlab.)

说明：  实现基2时域频域抽取fft算法，可输出运算后所得复序列的模值序列，并可记录显示计算所用时间(Achieve base 2 fft algorithm frequency domain extraction can be obtained after computing the output sequence of modulus of complex sequences can be used in the calculation time, records show)
