How to draw streamline

Hi, I have x and y data and u and v which are velocity components in a matrix. I want to draw streamlines. but matlab returns u and v must be at least 2*2 matrices. It does sense just when we have them as a function not as vectors. How can I draw streamlines in this condition? Thanks, Regards, Elham Mohammadi

Is there a plot in the gallery you'd like to recreate? http://www.mathworks.com/products/matlab/plot-gallery.html Or one from the help from stream()? Please supply some data and the code that you have tried.

Check quiver...

I have checked quiver as well. My issue is that the size of U and V is the same as X and Y. But it needs to have a matrix [m,n] = size(U) = size(V), which m and n are X and Y lenght.

quiver works when size of X,Y,U,V are same.

Thanks for the comment. quiver is now working. I also have the same issue with contour. for a X and Y vector I want to plot a parameter called SWS. The length of X and Y and SWS are m.
