利用matlab对暂态信号进行短时能量分析，频谱分析，以及短时傅里叶变换。(Use of matlab for short-term energy of the transient signal analysis, spectrum analysis, and short time Fourier transform.)

说明：  数据太多，复制粘贴麻烦，将多个数据文件合成一个文数据文件，(so much data ,it s trouble that use copy and past function. So make progran make more files synthesis one file )

The future 980 version of LS-DYNA will include Computational Fluid Dynamics (CFD) solvers. The main objective of these new solvers will be to perform fluid structure interactions by directly solving the Navier-Stokes equations and by using any LS-DYNA Lagrangian model for the solid part.

fit_mix_2D_gaussian - fit parameters for a 2D mixed-gaussian distribution using EM algorithm format: [u,covar,t,iter] = fit_mix_2D_gaussian( X,M ) input: X - input samples, Nx2 vector M - number of gaussians which are assumed to compose the distribution output: u - fitted mean for each gaussian (each mean is a 2x1 vector) covar - fitted covariance for each gaussian. this is a 2x2xM matrix. t - probability of each gaussian in the complete distribution iter - number of iterations done by the function
