Hi everybody, i have a problem on modeling of the delta function in the numerical calculations. i am working on an topic related to the random process, and there is the delta function in this process. i must model the delta function and there are several articles containing the equations for modeling of the delta function. you can see the equations below picture.
Where Fi(t) and Fj(t') are random variables, Dij is the real number, and Xz is normally distributed random numbers. i don't modeling this delta function. thanks in advance.
