NAST2D_STREAK_MOVIE
Animations of NAST2D_F90 Streakline Data

NAST2D_STREAK_MOVIE is a MATLAB function which makes a movie from an NAST2D_F90 streakline file.

A streakline file contains the locations of a set of points as they are carried by a fluid flow through a region. A movie of the streaklines gives a vivid impression of the direction and strength of a flow, and its changes over time.
