Hello All,
Can I plot y- velocity component in matlab I I have u,v and mesh? How?

For that you can make one zero matrix of same size as X/Y/u/v and use quiver.
Let X , Y, u, v be your matrices.
O = zeros(size(X)) ;
% x-components
figure
quiver(X,Y,u,O) ;
% y-components
figure
quiver(X,Y,O,v)

Hello KSSV,
I have one more question, how do I plot velocity interface on the top of quiver? I tried for contour but it say I need to have square matrix for the same. I have columns for xdata, ydata, Vx and Vy. I am attaching picture for the referance. I need to plot black line on each set of blue quivers out off this. I tried plot(x,Vx) it didn't plot single black curve for single set of blue arrow.

n = 10 ;
x = zeros(n,1) ;
y = (1:n)' ;
u = rand(n,1) ;
v = zeros(n,1) ;
h = quiver(x,y,u,v,'scale',0) ;
hold on
plot(u,y,'b')
You need to play around with scale.
