Quiver plot - how to use in this case?

2 views (last 30 days)
Hi guys,
I have my latitude matrix (71x259), longitude matrix (71x259), and the geostrophic current matrices (u, and v components each are 71x259 size). Now, if I plot the quiver plot like this way -
quiver(lat,lon,u,v);
I get hundres of thousands of arrows (velocity vectors) that I attached with this post. But I would love to show only 15 to 20 for the clarity of my picture. Can you please help me on reducing the numver of the arrows?

Try the following:
quiver(lat(1:5:end, 1:10:end),lon(1:5:end, 1:10:end),u(1:5:end, 1:10:end),v(1:5:end, 1:10:end));

Hi, thank you so, so much. Do you know how can I change the size/color of the arrows and arrow heads?
