MAX    Largest component.
    For vectors, MAX(X) is the largest element in X. For matrices,
    MAX(X) is a row vector containing the maximum element from each
    column. For N-D arrays, MAX(X) operates along the first
    non-singleton dimension.
 
    [Y,I] = MAX(X) returns the indices of the maximum values in vector I.
    If the values along the first non-singleton dimension contain more
    than one maximal element, the index of the first one is returned.
 
    MAX(X,Y) returns an array the same size as X and Y with the
    largest elements taken from X or Y.  Either one can be a scalar.
 
    [Y,I] = MAX(X,[],DIM) operates along the dimension DIM. 
 
    When complex, the magnitude MAX(ABS(X)) is used, and the angle
    ANGLE(X) is ignored.  NaN's are ignored when computing the maximum.
 
    Example: If X = [2 8 4   then max(X,[],1) is [7 8 9],
                     7 3 9]
 
        max(X,[],2) is [8    and max(X,5) is [5 8 5
                        9],                   7 5 9].
