1function C = true (varargin)
2%TRUE a logical matrix with all true values.
3%
4%   C = true (n) ;      n-by-n GrB logical matrix of all true entries.
5%   C = true (m,n) ;    m-by-n GrB logical matrix of all true entries.
6%   C = true ([m,n]) ;  m-by-n GrB logical matrix of all true entries.
7%   C = true (..., type) ;      matrix of all true entries of given type.
8%   C = true (..., 'like', G) ; matrix of all true entries, same type as G.

10% Since function overloads the MATLAB built-in true(...), at least one
11% input must be a GraphBLAS matrix to use this version (for example,
12% C = true (GrB (n))).
