sinpi

---

Computes sin(X * pi) accurately.

---

Syntax

---

res = sinpi(x)

Input argument

---

x

a numeric value

Output argument

---

res

a numeric value

Description

---

res = sinpi(x) computes sin(x * pi) accurately.

For odd integers, sinpi(x / 2) is +1 or -1.

For integers, sinpi(x) is exactly zero.

Example

---

x = [0, 1/2, 1, 3/2, 2];
r = sin(x * pi)
res = sinpi(x)
