Y = asin(X)Y = asinh(X)
asin and asinh operate element-wise on matrices. Their domains and ranges include complex values. All angles are measured in radians.
asin(X) returns the inverse sine for each element of X. For real elements of X in the range [-1,1], asin(X) is in the range [-pi/2,pi/2]. For real elements of X outside the range [-1,1], asin(X) has nonzero imaginary parts.
asinh(X) returns the inverse hyperbolic sine for each element of X.
-1 <= x <= 1.
