Almost. It has an additional coord scaling into the CubicNoise function, but the principle is the same - generate an array of values:

for (int x = 0; x < SizeX; x++)
{
    double NoiseX = StartX + (EndX - StartX) * x / SizeX;  // Go from StartX to EndX in SizeX steps
    for (int y = 0; y < SizeY; y++)
    {
        double NoiseY = StartY + (EndY - StartY) * y / SizeY;  // Go from StartY to EndY in SizeY steps
        CubicNoise2D(NoiseX, NoiseY);
    }
}

Similarly for a 3D version, it adds another dimension.
