function C = bitshift (A, B, assumedtype)
%BITSHIFT bitwise left and right shift.
% C = bitshift (A,B) is the bitwise shift of A; if B > 0 then A is shifted
% left by B bits, and if B < 0 then A is shifted right by -B bits. If
% either A or B are scalars, they are expanded to the pattern of the other
% matrix. C has the pattern of A (after expansion, if needed).
%
% With a third parameter, C = bitshift (A,B,assumedtype) provides a data
% type to convert A to if it is a floating-point type. If A already has
% an integer type, then it is not modified. Otherwise, A is converted to
% assumedtype, which can be 'int8', 'int16', 'int32', 'int64', 'uint8',
% 'uint16', 'uint32' or 'uint64'. The default is 'uint64'.
%
% Example:
%
% A = uint8 (magic (4))
% G = GrB (magic (4), 'uint8') ;
% C1 = bitshift (A, -2) ;
% C2 = bitshift (G, -2)
% isequal (C2, C)

% GrB/bitset, GrB/bitclr.
