asin - Inverse sine; result in radians
Syntax
Y = asin(X)
Description
Y = asin(X) returns the
inverse sine (arcsine) for each element of X. The asin function
operates element-wise on arrays. The function's domains and ranges
include complex values. All angles are in radians. For real elements
of X in the domain [-1,1], asin(X) is
in the range
. For real elements of x outside
the range [-1,1], asin(X) is
complex.
Definitions
The arcsine is defined as:
