<BODY><PRE>function out=3Dmaxloc(x,dim)
%function out=3Dmaxloc(x,dim)
%
% Replicates the functionality of maxloc in fortran.
%
% INPUTS: x -> data variable =20
% dim -> (optional) dimension upon which to operate
% (same in Fortran and Matlab)
%
% OUTPUTS: out -> set to second output of Matlab's max() if dim =
is specified
% otherwise, is the maximum location for the entire =
array
% returned as a cell array resulting from ind2sub
% this could then be used as a subscript list
%
% EXAMPLES: a=3Dmagic(5); b=3Dmaxloc(a); a(b{:}),b
% b=3Dmaxloc(a,1)
