How can I extract the velocity profiles from quiver plot?

I'm trying to post-process my simulation data an to calculate the momentum and displacement thicknesses (Fluent) for flow over a cylinder problem. The velocity vectors in matlab can be seen below:

I want to extract the velocities ona radial lines at each theta position around cylinder. How can I do that?

Thanks in advance,

Already you have data in hand right? What elese you want to extract?

I have the data, but for the boundary layer calculations I need velocities in a specific order as below image.

At each theta value (each radial red line in image), velocity should be extracted as profile and I need an array like below.

This you can achieve by using interpolation. Read about interp2. You have (X,Y) already. Make your required points at which you want velocities and use interp2 for (u,v) components seperately.

Thanks you for your suggestion, I'll try it.

It worked! Thank you for the valuable advise.
