velocity_triangulation.m v1.0 (Sep 2009)

Triangulates velocity from a 2D planar wave.

Description

This function finds the velocity of a 2-dimensional planar wave from at least 2 sensors, by specifying its location (x,y) or (lon,lat) and its respective arrival time.

It returns the speed and direction (or tracking if coordinates were given):
>> [VEL,DIR] = velocity_triangulation(x,y,time,TOL);
where TOL is a tolerance time. You may get a figure with the results, like the one shown in the screenshot. Just take a look to the optional arguments.

Enjoy it!
Any comments and bugs reports will be very appreciated!

• MATLAB release: MATLAB 7.7 (R2008b)
• Other requirements: If coordinated are use, the program requires the Mapping Toolbox or the M_MAP Toolbox by Rich Pawlowicz.
