acscd

Inverse cosecant in degrees

Usage

acscd(A)

• A should be an array, which can be real or complex.
• It returns an array containing the inverse cosecant (in degrees) of each element of A.
• For real elements of A lying in $(-1,1)$, it returns complex numbers.
• The output has the same size as A.

Example

Input

• acscd(A) gives a complex number when abs(A) is less than 1.
• acscd(0) gives NaN + NaN i.

x = linspace(-1,1,8)
acscd(x)

Output

x = 
-1.0000  -0.7143  -0.4286  -0.1429   0.1429   0.4286   0.7143   1.0000
