DESCRIPTION
The acosd2 function
returns a vector of the arc cosines of the elements of x. Inputs
must be within the interval [-1,+1].
RETURN VALUE
The function
acosd2 returns
a double vector in which each element is defined as:
- the arc cosine of the corresponding element of x, if the element
of x is within the interval [-1,+1],
- undefined otherwise.
Each element in the return vector is expressed in radians.
