%GRB.VREDUCE reduce a matrix to a vector.

% C = GrB.vreduce (monoid, A)
% C = GrB.vreduce (monoid, A, desc)
% C = GrB.vreduce (Cin, M, monoid, A)
% C = GrB.vreduce (Cin, M, monoid, A, desc)
% C = GrB.vreduce (Cin, accum, monoid, A)

% C = GrB.vreduce (Cin, M, accum, monoid, A)
% C = GrB.vreduce (Cin, M, accum, monoid, A, desc)
%
% The monoid and A arguments are required. All others are optional.
%
% Monoids for real non-logical types: '+', '*', 'max', 'min', 'any'
% For logical: '|', '&', 'xor', 'eq', 'any'
% For complex types: '+', '*', 'any'
% For integer types: 'bitor', 'bitand', 'bitxor', 'bitxnor'
%
% See 'help GrB.monoidinfo' for more details on the available monoids.
%
% By default, each row of A is reduced to a scalar. If Cin is not present,
% C (i) = reduce (A (i,:)). In this case, Cin and C are column vectors of
% size m-by-1, where A is m-by-n. If desc.in0 is 'transpose', then A.' is
% reduced to a column vector; C (j) = reduce (A (:,j)). In this case, Cin
% and C are column vectors of size n-by-1, if A is m-by-n.
