Name
csch — Computes the element-wise hyperbolic cosecant of the
    argument.
Calling Sequence
y = csch(x)
Parameters
- x
- Real or complex array. 
- y
- Real or complex array with same dimensions as
          - x.
 
Description
Computes the element-wise hyperbolic cosecant of the argument. For
    real data the results are real.
Examples
 
x=linspace(0.01,4,200);x=[-x($:-1:1) %nan x];
clf();
plot(x,csch(x))
