 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 X is complex, the maximum is computed using the magnitude
    max(ABS(X)). In the case of equal magnitude elements, then the phase
    angle max(ANGLE(X)) is used.

    max(..., NANFLAG) specifies how NaN (Not-A-Number) values are treated.
    NANFLAG can be:
    'omitnan'    - Ignores all NaN values and returns the maximum of the
                   non-NaN elements.  If all elements are NaN, then the
                   first one is returned.
    'includenan' - Returns NaN if there is any NaN value.  The index points
                   to the first NaN element.
    Default is 'omitnan'.

    Example: If X = [2 8 4; 7 3 9] then
                max(X,[],1) is [7 8 9],
                max(X,[],2) is [8; 9] and
                max(X,5)    is [5 8 5; 7 5 9].
