I have the following system :
dxdt = A.*x.^2 ;
how can I find a PDF for this system for different values of A and t = 0:0.1:100?
Regards

What do you want to be stochastic in the above ODE ?

You can use ksdensity, but if you use enough random numbers for A0, a histogram will give you the same quality for the pdf.
Normfit, normpdf etc. can not be used because even if you assume that A0 is normally distributed, x(t,A0) usually won't.
You will have to find out what distribuion x(t,A0) follows if you assume a certain distribution type for A0.
