function C = bitand (A, B, assumedtype)
%BITAND bitwise AND.
% C = bitand (A,B) is the bitwise AND of A and B. If A and B are
% matrices, the pattern of C is the set intersection of A and B. If one
% of A or B is a nonzero scalar, the scalar is expanded into a sparse
% matrix with the same pattern as the other matrix, and the result is a
% sparse matrix.
%
% With a third parameter, C = bitand (A,B,assumedtype) provides a data
% type to convert A and B to if they are floating-point types. If A or B
% already have integer types, then they are not modified. Otherwise, A or
% B are converted to assumedtype, which can be 'int8', 'int16', 'int32',
% 'int64', 'uint8', 'uint16', 'uint32' or 'uint64'. The default is
% 'uint64'.
%
% The input matrices must be real, and may be GraphBLAS/built-in
% matrices, in any combination. C is returned as a GraphBLAS matrix.
% The type of C is given by GrB.optype (A,B), after any conversion to
% assumedtype, if needed.
%
% Example:
%
% A = GrB (magic (4), 'uint8')
% B = GrB (13 * eye (4), 'uint8') ;
% B (3,4) = 107
% C = bitand (A, B)
% fprintf ('\nA: ') ; fprintf ('%3x ', A) ; fprintf ('\n') ;
% fprintf ('\nB: ') ; fprintf ('%3x ', B) ; fprintf ('\n') ;
% fprintf ('\nC: ') ; fprintf ('%3x ', C) ; fprintf ('\n') ;
% C2 = bitand (uint8 (A), uint8 (B))
% isequal (C2, C)
