function G = deserialize (blob, mode, arg3)
%GRB.DESERIALIZE convert a serialized blob into a matrix.
% G = GrB.deserialize (blob) returns a @GrB matrix constructed from the
% uint8 array blob constructed by GrB.serialize.
%
% G = GrB.deserialize (blob) or GrB.deserialize (blob, 'fast') assume the
% blob comes from a trusted source. G = GrB.deserialize (blob, 'secure')
% does a secure (but slow) deserialization, checking the blob to ensure it
% is valid, when the blob might not be trusted.
%
% Example:
% G = GrB (magic (5))
% blob = GrB.serialize (G) ;
% f = fopen ('G.bin', 'wb') ;
% fwrite (f, blob) ;
% fclose (f)
% clear all
% f = fopen ('G.bin', 'r') ;
% blob = fread (f, '*uint8') ;
% G = GrB.deserialize (blob)
%
% See also GrB.serialize, GrB.load, GrB.save, GrB/struct.

% rules for casting floating-point to integers are used (truncation), not
% the MATLAB rules (rounding to nearest integer).
