ASEC Inverse Secant Function

Section: Mathematical Functions


Computes the inverse secant of its argument. The general syntax for its use is
  y = asec(x)

where x is an n-dimensional array of numerical type.

Function Internals

The acosh function is computed from the formula


Here is a simple plot of the inverse secant function
--> x1 = -5:.01:-1;
--> x2 = 1:.01:5;
--> plot(x1,asec(x1),x2,asec(x2)); grid('on');
