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.
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');
