I realized now, even if I knew how to write, since I do not use matlab, and perform calculations have it

ok, I already found one mistake there was to be no x, y and i, jfor i =1:n for j =1:n u(i,j) = 0.5 + i; v(i,j) = 1 + 5*j; end end at t = 0 is good, but in other cases(t=0.25; t=0.75), my u = NaN go in and I'm stuck at this point

Hello, I have a project (model reaction diffusion brusselator 2d) ∂u/∂t=A+u^2v-(B−1)u+D1((∂^2)u/∂(x^2)+(∂^2)u/∂(y^2)) ∂v/∂t=Bu−u^2v+D2((∂^2)v/∂(x^2)+(∂^2)v/∂(y^2)) initial conditions: u(x,y,0) = 0.5 + y, v(x,y,0) = 1 + 5x. boundary conditions: ∂u/∂n = 0, ∂v/∂t = 0 n-external normal to the...
