-% RANGE = showIm (MATRIX, RANGE, ZOOM, LABEL, NSHADES )
-% 
-% Display a MatLab MATRIX as a grayscale image in the current figure,
-% inside the current axes.  If MATRIX is complex, the real and imaginary 
-% parts are shown side-by-side, with the same grayscale mapping.
-% 
-% If MATRIX is a string, it should be the name of a variable bound to a 
-% MATRIX in the base (global) environment.  This matrix is displayed as an 
-% image, with the title set to the string.
-% 
-% 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.
-% 
-% ZOOM specifies the number of matrix samples per screen pixel.  It
-% will be rounded to an integer, or 1 divided by an integer.  A value
-% of 'same' or 'auto' (default) causes the zoom value to be chosen
-% automatically to fit the image into the current axes.  A value of
-% 'full' fills the axis region (leaving no room for labels).  See
-% pixelAxes.m.
-% 
-% If LABEL (optional, default = 1, unless zoom='full') is non-zero, the range 
-% of values that are mapped into the gray colormap and the dimensions 
-% (size) of the matrix and zoom factor are printed below the image.  If label 
-% is a string, it is used as a title.
-% 
-% NSHADES (optional) specifies the number of gray shades, and defaults
-% to the size of the current colormap.
