function [mn,idx,col]=minn(A)
%MINN N-D Array Minimum.
% MINN(A) returns the minimum value found in the array A.
%
% [MN,Row,Col] = MINN(A) for 2-D A returns the minimum value MN as well as
% the row and column subscripts where the minimum appears. Row and Col are
% column vectors if multiple minimums appear in A.
%
% [MN,Idx] = MINN(A) returns the minimum value MN as well as the linear
% indices Idx of all elements in A that are equal to MN.
% To get the row, column, ..., subscripts associated with the linear indices
% use IND2SUB(size(A),Idx).
