function y = sinhint(x) % SINHINT Hyperbolic sine integral function % Y = SINHINT(X) represents the hyperbolic sine integral function, which % is defined as: % % sinhint(x) = int(sinh(t)/t,t,[0,x]) % % sinhint(x) returns the special values: % % sinhint(0) = 0, % sinhint(inf) = inf, % sinhint(-inf) = -inf. % % For all other symbolic arguments, sinhint returns symbolic function % calls. % % See also SIN, SINH, SININT, SSININT. % Copyright 2013 The MathWorks, Inc. y = privUnaryOp(x,'symobj::map','Shi'); end
