asec

Inverse secant

Syntax

• Y = asec(X)
  

Description

Y = asec(X) returns the inverse secant (arcsecant) for each element of X.

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

Examples

Graph the inverse secant over the domains and .

• x1 = -5:0.01:-1;
  x2 = 1:0.01:5;
  plot(x1,asec(x1),x2,asec(x2)), grid on
  
  
  

Definition

The inverse secant can be defined as

Algorithm

asec uses FDLIBM, which was developed at SunSoft, a Sun Microsystems, Inc. business, by Kwok C. Ng, and others. For information about FDLIBM, see http://www.netlib.org.
