acosd
Inverse cosine in degrees
Syntax
Description
returns the
inverse cosine (cos-1) of the elements of
Y
= acosd(X
)X
in degrees. The function accepts both real and complex inputs.
For real values of
X
in the interval [-1, 1],acosd(X)
returns values in the interval [0, 180].For values of
X
outside the interval [-1, 1] and for complex values ofX
,acosd(X)
returns complex values.
