 Usage

Computes the csc function for its argument. The general
syntax for its use is

    y = csc(x)

where x is an n-dimensional array of numerical type. Integer
types are promoted to the double type prior to calculation
of the csc function. Output y is of the same size and type
as the input x, (unless x is an integer, in which case y is
a double type).


 Internals

Mathematically, the csc function is defined for all
arguments as
 \[ \csc x \equiv \frac{1}{\sin x}. \]


 Example

The following piece of code plots the real-valued csc(2 pi
x) function over the interval of [-1,1]:

  --> t = linspace(-1,1,1000);
  --> plot(t,csc(2*pi*t))
  --> axis([-1,1,-10,10]);
