Description

• 

The sine integral is defined for all complex x as follows:

Six=0xsinttⅆt

• 

When x is a container object such an Array or list, the sinint(x) function computes the element-wise sine integral of x.  For example when x is a Matrix the result R is formed as R[i,j] = Si(x[i,j]).

• 

When x is numeric, sinint(x) is equivalent to Si(x).
