WebIn the case of the normal distribution it holds that the moment generating function (mgf) is given by M ( h) = exp ( μ h + 1 2 σ 2 h 2), where μ is the mean and σ 2 is the variance. Thus the cumulant generating function C ( h) which is given by C ( h) = ln ( M ( h)) reduces to C ( h) = μ h + 1 2 σ 2 h 2. I am sure you can evaluate this in Matlab.
