SVD

计算fft，输出频谱，相位，模值,Calculation of FFT, the output frequency, phase, amplitude,

通过对钢轨和车轮的ansys有限元建模，分析在钢轨的接头处的动力学特性。(Rail and wheel ansys finite element modeling, analysis of the dynamics of the rail joints.)

以上是两个内点法程序，原仿射内点法，对偶仿射内点法。初始内点需要自己给出，自动求解初始内点的程序下次发送(These are the two interior point method procedure, the original affine interior point method, dual affine interior point method. Initial interior point needs its own given the initial interior point solution of automatic procedures to send the next)

完成了复数矩阵的计算,采用了并行算法原理，较快速的处理了稀疏矩阵方程结构。(Completed a complex matrix computation, parallel algorithm principle, more rapid processing of the sparse matrix equation structure.)
