Web用matlab写了一个解扩散方程的程序(用的是老师给的程序),可是运行显示出错,哪位高手帮帮忙! 华中科技大学排名 • 2天前 • 软件运维 • 阅读0 %只修改了一点语法错误,修正了向量维数,没对数据做任何修改: The Gray-Scott equations are a pair of coupled reaction-diffusion equations that lead to interesting patterns [1,2,3]. Let us look at two examples in 2D. The equations are ut=ε1Δu+b(1−u)−uv2,vt=ε2Δv−dv+uv2, where Δ is the Laplacian and ε1,ε2,b,dare parameters. To begin with we choose these values. We now solve … See more If we change the values of the parameters just a bit, the nature of the solution changes fundamentally. Now we see spots instead of rolls. See more Not all choices of parameters lead to interesting pictures. With b=0.02 and d=0.08, for example, the functions converge to constants. See more P. Gray and S. K.
