Inverse hyperbolic cosecant
Y = acsch(X)
The acsch function operates element-wise on arrays. The function's domains and ranges include complex values. All angles are in radians.
Graph the inverse hyperbolic cosecant over the domains –20 ≤ x ≤ –1 and 1 ≤ x ≤ 20.
x1 = -20:0.01:-1; x2 = 1:0.01:20; plot(x1,acsch(x1),x2,acsch(x2)), grid on
