Overlaying a map on matlab with a quiver plot

I have a set of u and v wind data (41 longitude points around the world by 19 latitude points from 40N to 40S) that I am plotting with the quiver function on matlab. I want to overlay this onto a simple cylindrical map of the area of the world I am plotting the data for.

I have a simple cylindrical map of the area with the coasts by using the matlab mapping toolbox and have tried to use the hold on command to plot the data over the map however this does not work. I thought this would be a lot easier as it seems like it would be such a common use of Matlab.

Any suggestions on how to do this as the mapping documentation is extremely complex?
