1function C = acosh (G) 2%ACOSH inverse hyperbolic cosine. 3% C = acosh (G) is the inverse hyperbolic cosine of each entry G. 4% Since acosh (0) is nonzero, the result is a full matrix. 5% C is complex if any (G < 1). 6% 7% See also GrB/cos, GrB/acos, GrB/cosh. 8 9% SuiteSparse:GraphBLAS, Timothy A.
