[問題] Laplace's Equation
我想解一個Laplace's Equation
比方說下面這個文件第三頁這種例題
http://www.robots.ox.ac.uk/~jmb/lectures/pdelecture5.pdf
輸入
NDSolve[{D[u[x, y], x, x] + D[u[x, y], y, y] == 0, u[0, y] == 0,
u[x, 0] == 0, u[3, y] == 0, u[x, 4] == Sin[Pi/3*x]}, u, {x, 0,
3}, {y, 0, 4}]
結果她回傳
NDSolve::ivone: Boundary values may only be specified for one independent
variable. Initial values may only be specified at one value of the other
independent variable.
請問哪裡寫錯了
謝謝~
