Syntax

Y = acsch(X)

Description

Y = acsch(X)returns the inverse hyperbolic cosecant for each element ofX.

Theacschfunction operates element-wise on arrays. The function's domains and ranges include complex values. All angles are in radians.

Inverse Hyperbolic Cosecant

For real values x in the domain x < 0 and x > 0 , the inverse hyperbolic cosecant satisfies

csch − 1 ( z ) = sinh − 1 ( 1 z ) = log ( 1 x + 1 x 2 + 1 ) .

For complex numbers z = x + i y , the callacsch(z)returns complex results.
