The file begins with the characters %!PS, which, when sent to a
printer, tells the printer to interpret the rest of the file as PostScript
language commands, and not as text to be printed. Lines beginning
with percent characters “%” are comments and are, except for the first
line, ignored by the printer. Actual PostScript commands begin with
forward slashes “/”. The line here that reads:

%%BoundingBox: (atend)

says that the bounding box is to be found at the end of the file.
If you print the same graphic using matlab’s Encapsulated
PostScript option (print -deps file ), the first few lines of file.eps
will look like this:

The crucial difference is that the bounding box information appears near
the start of the file. The bounding box is of the form xll yll xur yur,
where:
xll is the x coordinate of the lower left corner of the graphic,
yll is the y coordinate of the lower left corner of the graphic,
xur is the x coordinate of the upper right corner of the graphic,
