Computes the asin function for its argument. The general
syntax for its use is
y = asin(x)
where x is an n-dimensional array of numerical type.
Integer types are promoted to the double type prior to
calculation of the asin function. Output y is of the
same size and type as the input x, (unless x is an
integer, in which case y is a double type).
Mathematically, the asin function is defined for all
arguments x as
For real valued variables
x in the range [-1,1], the function is
computed directly using the standard C library's numerical asin
function. For both real and complex arguments x, note that generally
due to the periodicity of
sin(x).
The following code demonstates the asin function over the range
[-1,1].
--> t = linspace(-1,1); --> plot(t,asin(t))
