Yes:

Add two vector and multiply by a third.

Method 1:

Code:

Vector<int, 16> a, b, c;
auto temp = VecMath::Add(a,b);
Vector<int, 16> result = VecMath::Multiply(temp, c).Evaluate();

Note no actually computation is done until the .Evaluate Method.

Method 2:

Code:

Vector<int, 16> a, b, c;
Vector<int, 16> result = (a + b) * c;

In this case this code would compile to a program that generates the actual implementation.

Method 3:

Code:

a :: Vector Int 16
b :: Vector Int 16
c :: Vector Int 16
result = (a + b) * c

This would then be compiled to the code required

Method 4:

C++

Code:

int a[16], b[16], c[16];
int result[16];
for (int i = 0; i < 16; i++) result[i] = (a[i] + b[i]) * c[i];

openCL

Code:

int16 a, b, c;
int16 result;
result = (a + b) * c;

openGL ES

Code:

int16 a, b, c;
int16 result;
result = (a + b) * c;

OpenCL and OpenGL ES have significant differences not shown here so would need separate implementations.
