Hello,
I have a quick question regarding the use of a pseudo-random scource inside NDsolve.
Suppose you have the following:
scource[z_,]:= RandomReal[{-5,5}]
Then in NDsolve we have
NDsolve[f'[z] + f[z] == scource[z],f,{z,0.5}]
My question is as the integrator works to solve this system within NDsolve is it really putting in a random number at each z-step? or is it just evaluated scource[z] once and returning a number, and then going into the integrator?'
Nevertheless, How can I keep the algorithm that is actually solving this system to pull random numbers at each z step?
Thanks,
-Clint
