sinint - Sine integral

Syntax

Description

Y = sinint(X) evaluates the sine integral function at the elements of X, a numeric matrix, or a symbolic matrix. The result is a numeric matrix. The sine integral function is defined by

Examples

Evaluate sine integral for the elements of the matrix:

sinint([pi 0;-2.2 exp(3)])

ans =
    1.8519         0
   -1.6876    1.5522

The statement

sinint(1.2)

returns

ans =
1.1080

The statement

syms x;
diff(sinint(x))

returns

ans =
sin(x)/x
