Hi,
I am plotting velocity vectors and streamlines using the below code. I getting the proper velocity vectors, but not streamline (please see figure). Please somebody help me with this....
skip=2;
ff=quiver(x',y(1:skip:end),Um(1:skip:end,:),Vm(1:skip:end,:));
ff.Color='black';
ff.AutoScaleFactor=12;
set(gca, 'YDir','normal')
startx = -40:40;
starty = 0:80;
streamline(x,y,Um,Vm,startx,starty);

Where do you want your streamlines to originate? Right now, every line starts at a different y-coordinate, you might want to change starty to something uniform like starty = ones(size(startx)) and take a look at the example here.
Cheers
