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).
Mathematically, the csc
function is defined for all arguments
as
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]);
