I have a systems of time dependent pde's representing population growth and depletion/production of resources. I would like to set the code so that the values of the solutions are not negative (not physical). I am using solvepde, I thought that maybe I could add:
odeoptions=odeset(odeoptions,'NonNegative',1)
in the 72nd line of solveTimeDependent.m but matlab tells me to that my access is denied.
What should I do?
9.0.0.341360 (R2016a)
