How to solve stream function
显示 更早的评论
I am trying to get stream function which expressed as s(x,y)
ds/dy=u=0.5+1.2.*x;
ds/dx=v=-2-1.2*y;
clc,clear;
syms s(x,y) x y
u=0.5+1.2.*x+y;
v=-2-1.2*y+x;
eqn =[diff(s,y) ==u,diff(s,x)==v]
ySol(x,y) = dsolve(eqn)
It seems wrong. Can you please help me ?

Hi,
dsolve() can't be used here.
Here is the good explantion how to solve your exercise: https://www.mathworks.com/matlabcentral/answers/362434-stream-function-from-velocity-vector-map
You'd need to employ pdepe() to solve this exercise.
