How to plot streamlines for a fea unstructured mesh with given u,v velocities?

I have a unstructured mesh with node coordinates and respective u,v velocities. The streamline plot fucntion needs monotonic data, is there any other way to plot stream lines using unstructured mesh?

    % try 

quiver(x,y,u,v)

I need streamlines plot too. Thank you

Use griddata to create monotonic data

[biot0p]

Typically meshes that come from complex geometries of FEA are actually unstructured, so griddata would not work in this case.

i found this link here, that plots steamlines from meshes, but one of the functions used (tsearch) is deprecated. It would be great if streamline simply had a way of plotting with meshes, like quiver does!
