function C = int64 (G)
%INT64 cast a GraphBLAS matrix to built-in full int64 matrix.
% C = int64 (G) typecasts the GrB matrix G to a full int64 matrix.  The
% result C is full since sparse int64 matrices are not built-in.
%
% To typecast the matrix G to a GraphBLAS sparse int64 matrix instead,
% use C = GrB (G, 'int64').
