acsc

Inverse cosecant in radians

Usage

acsc(A)

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

Example

Input

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

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

Output

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