Inverse hyperbolic cotangent
Y = acoth(X)
The acoth function operates element-wise on arrays. The function's domains and ranges include complex values. All angles are in radians.
Graph the inverse hyperbolic cotangent over the domains –30 ≤ x < –1 and 1 < x ≤ 30.
x1 = -30:0.1:-1.1; x2 = 1.1:0.1:30; plot(x1,acoth(x1),x2,acoth(x2)), grid on
