% SCRANGE return the min and max of the input array
%
%         scrange(x) returns the min and max of the input array.
%         If x is a vector, SCRANGE returns the minimum and
%         maximum values. 
%         If x is a matrix, SCRANGE returns the minimum and
%         maximum values of each column.  
%
%         SCRANGE is most useful in determining the range of vector 
%         data to be passed to LCONTOUR2.
%
%         Example: >> x = 1:10;
%                  >> scrange(x)
%                  min = 1
%                  max = 10
