CSC Trigonometric Cosecant Function

Section: Mathematical Functions


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).

Function Internals

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]);
