Coefficient Handle for Nonconstant Coefficients
显示 更早的评论
In specifyCoefficients there is an option to choose the coefficient "f" as a non-constant, for instance in the following form:
f = @(location,state)location.y.^2.*tanh(location.z)/1000;
I need to set f as follows:
a=@(t,z) interp2(XX,TT,V,t,z);
f = @(location,state) a(location.y,location.x);
This gives the following error:
Error using pde.PDEModel/solveStationaryNonlinear (line 27)
Unsuitable initial guess U0 (default: U0=0).
Error in pde.PDEModel/solvepde (line 77)
