How to solve stream function

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.
