csch
csch(X) computes hyperbolic cosecant for each element of X.
Examples
> x = (0:0.05:pi)'
[x:63x1 double]
> plot([-x x], [csch(-x) csch(x)], struct('colors', {'blue'}))
[ans:1x1 struct]
> x = (0:0.05:pi)'
[x:63x1 double]
> plot([-x x], [csch(-x) csch(x)], struct('colors', {'blue'}))
[ans:1x1 struct]
