 % UTIL_plotMatrix general purpose plotting utility for plotting the results
 %  of the MAP auditory model.
 % All plots are placed in subplots of a figure (default figure 1).
+%
 % Input arguments:
 % 	'toPlot' is matrix (either numeric or logical)
 % 	'method' is a structure containing plot instructions
 %
-%   surface plots have log z-axis when all values are >1
-%
-% when calling this function, always increment the subPlotNo in method
-% 	method.subPlotNo=method.subPlotNo+1;
-% 	method.subPlotNo=method.subPlotNo;
-%
 % mandatory parameters:
-% 	method.displaydt			xValues spacing between data points
-% 	method.numPlots      total number of subPlots in the figure
-% 	method.subPlotNo     number of this plot
-%   method.yValues 		mandatory only for 3D plots
+% 	method.displaydt		xValues spacing between data points
+%   method.yValues          yaxis labels mandatory only for 3D plots
 %
 % optional
-% 	method.figureNo      normally figure(1)
-% 	method.zValuesRange 	[min max] value pair to define yaxis limits
-%   method.zValuesRange  [min max] CLIMS for 3-D plot
-% 	method.yLabel 		(string) y-axis label
-% 	method.xLabel		(string) x-axis label
-% 	method.title  		     (string) subplot title
+% 	method.figureNo         default figure(1)
