Superimpose the graph of a function onto a streamline field

Hi, I have to plot a streamline field given a 2D velocity vector and then superimpose 2 other functions (streamlines at given points) over it. I have already written the code for the streamline field, but am lost as to how I can plot the other functions along with the field in the same figure. How can I go about doing this? Thanks, David

The code I am using:

close all;
clc;
clear all;

xmin=-1;
xmax=1;
ymin=-1;
ymax=1;
h=0.6;

[x,y] = meshgrid(xmin:h:xmax,ymin:h:ymax);
u = y./(x.^2+y.^2);
v = -x./(x.^2+y.^2);

figure
quiver(x,y,u,v)
startx = xmin:h:xmax;
starty = ymin:h:ymax;
h = streamline(x,y,u,v,startx,starty);
set(h,'color','red')

Hey David,

You can try using hold on function.

One such example can be found here.
