SININTEGRAL function

Description

SININTEGRAL(x) returns the value of the sine integral function of x. The sine integral function is defined as:

$$ {\rm Si}(x) = \int_0^x\frac{\sin t}{t}\,dt $$

The argument x can be a real number or a matrix. When it is a matrix, the function returns a matrix with the same dimensions and with the SININTEGRAL function applied to all elements.
