For me, Matlab processing has worked well with big as well as "normal"
files.  It's produced summary tables, files, and figures from multicolumn
text files so long they had to be processed in segments, read in sequential
parts from the remote source file.  It's read multiple files in Excel or
text formats, for big-batch processing.   It's read technical videos,
processing data one or a few frames at a time, in sensor simulations.
And, it provides good control of figures, including 3D graphs that can
be rotated to different view angles (manually or automatically rotated
for display or for .avi videos), contour graphs, and all the standard
2D plot styles.

Cheers,
