There are three ways: Quickest way: Create a directory called C:\GS Copy all files in the directory $MATLAB\GHOSTSCR\BIN , $MATLAB\GHOSTSCR\PS_FILES, and $MATLAB\GHOSTSCR\FONTS to C:\GS (where $MATLAB represents the MATLAB root directory) Copy the PostScript file to C:\GS CD to C:\GS Execute the command GS386 where is the whole name, including the .ps extension. If for some reason this doesn’t work, try DOS4GW GS386 . Clean but somewhat cumbersome: CD to the $MATLAB\GHOSTSCR\BIN directory Execute the command GS386 -I..\PS_FILES -I..\FONTS where here represents the full path name to the postscript file. Clean and easy but more permanent: Add $MATLAB\GHOSTSCR\BIN to your DOS path. In the AUTOEXEC.BAT file, set an environment variable called GS_LIB as follows: set GS_LIB = $MATLAB\GHOSTSCR\PS_FILES;$MATLAB\GHOSTSCR\FONTS (where $MATLAB is replaced by the MATLAB root directory.)
