I would like to run the MATLAB script that performs FTDT here: http://www.antenna-theory.com/antennas/patches/patch6.php

However, the script reads a file

A = dlmread('junk.0');

Where can I get junk.0? I couldn't find it on the page.

'junk.0' and the rest are just snapshots of the fields, generated by the fdtd.c program. So it outputs a list of numbers for the Ez component fo the field into a bunch of different files.

I think if you run the .c file [execute the code] it should dump out the output files for this script.

Right you are. I compiled and ran the c++ code and it worked great. Well, after some compatibility changes to the matlab script. In case anyone else has problems in Windows 7 and MATLAB R2012a I had to make these changes:

12: mov = VideoWriter(outfile);
13: open(mov)

46: writeVideo(mov, F);

85: F = getframe( figure(1), [0 0 560 420] );

89: close(mov);
