quiver plot on coastline map

Hi all

I have a matrix of m*n dimension for latitude, longitude, velocity components (u,v) I would like to plot this (quiver) on a coastline map.

how can I do that?

Thank you in advance.

I assume you read the documentation.

What's wrong with

 quiver(longitude,latitude,u,v)

[Lilya]

yes, I did.

but I am using m_map toolbox. so m_quiver is equivalent to quiver in this toolbox but it doesn't work ( the data doesn't appear on the map). is there a problem with the number of rows and columns?

[José-Luis]

I have no idea. The crystal ball is a bit fuzzy today. That sort of info is something that should have been included in the original question. The mind-reading toolbox is far from complete.

I don't think that toolbox is native.

I don't have your data.

I could speculate as to what is wrong but that is a woefully inefficient way of solving problems.

[Lilya]

I did it.

Thank you so much for your attention. appreciate it .

Hello

I met the same problem as you.

You can try quiverm instead.
