maxn

MAXN N-D Array Maximum.
 MAXN(A) returns the maximum value found in the array A.

 [MX,Row,Col] = MINN(A) for 2-D A returns the maximum value MX as well as
 the row and column subscripts where the maximum appears. Row and Col are
 column vectors if multiple maximums appear in A.

 [MX,Idx] = MAXN(A) returns the maximum value MX as well as the linear
 indices Idx of all elements in A that are equal to MX.
 To get the row, column, ..., subscripts associated with the linear indices
 use IND2SUB(size(A),Idx).
