NAST2D_CONTOUR
Contour Plots of NAST2D_F90 Data

NAST2D_CONTOUR is a MATLAB function which reads a datafile created by NAST2D_F90 (usually containing values of the streamfunction) and displays a contour plot.

Author:

NAST2D_CONTOUR was developed by Professor C David Pruett of James Madison University.

Usage:

nast2d_contour ( 'file_name' )

where file_name is an NAST2D_F90 data file.
