scipy.special.diric

scipy.special.diric(x, n)[source]

Returns the periodic sinc function, also called the Dirichlet function

The Dirichlet function is defined as:

diric(x) = sin(x * n/2) / (n * sin(x / 2)),

where n is a positive integer.

Parameters:

x : array_like

Input data

n : int

Integer defining the periodicity.

Returns:

diric : ndarray
