结合马尔科夫链的sir传染病建模

This m.file is intended to perform the numerical integration of a structural system subjected to an external dynamic excitation. The integration scheme utilized for this analysis is the newmark-wilson alpha-beta-theta method(collocation method). the collocation method is an implicit time steping scheme so stability of the system need not be considered.

We present in this paper a new method for blind source separation which is adapted to the case where the sources have different morphologies. We show that the morphology diversity concept leads to a new and very efficient method, even in the p

以n-hexane(1)/ethanol(2)/methylcyclopentane(3)/benzene(4) system为例计算该体系的泡点温度。使用了unifac活度系数法。【截图】cal_bubble_T.m

对于一般的标准形式线性规划问题(求极小问题)非常实用

%WAVELET  1D Wavelet transform with optional singificance testing %WAVELET 一维小波变换，具有可选的重要性测试 %   [WAVE,PERIOD,SCALE,COI] = wavelet(Y,DT,PAD,DJ,S0,J1,MOTHER,PARAM) % %   Computes the wavelet transform of the vector Y (length N), %   with sampling rate DT. % %   By default, the Morlet wavelet (k0=6) is used. %   The wavelet basis is normalized to have total energy=1 at all scales. % % % INPUTS: % %    Y = the time series of length N. %    DT = amount of time between each Y value, i.e. the sampling time. % % OUTPUTS: % %    WAVE is the WAVELET transform of Y. This is a complex array %    of dimensions (N,J1+1). FLOAT(WAVE) gives the WAVELET amplitude, %    ATAN(IMAGINARY(WAVE),FLOAT(WAVE) gives the WAVELET phase. %&n
