-% This format is accessible from the XV image browsing utility.
-%
-% RANGE (optional) is a 2-vector specifying the values that map to
-% black and white, respectively.  Passing a value of 'auto' (default)
-% sets RANGE=[min,max] (as in MatLab's imagesc).  'auto2' sets
-% RANGE=[mean-2*stdev, mean+2*stdev].  'auto3' sets
-% RANGE=[p1-(p2-p1)/8, p2+(p2-p1)/8], where p1 is the 10th percentile
-% value of the sorted MATRIX samples, and p2 is the 90th percentile
-% value.
-%
-% TYPE (optional) should be 'raw' or 'ascii'.  Defaults to 'raw'.
