Returns evaluated point from the given n-dimensional polynomial.
t is clamped in the range [0,1].
| coefficients | 2-dimensional array flattened to 1-dimensional array. coefficients[degree][dimension] -> coefficients[degree * dimension] |
Returns smoothly interpolated value in the range [0,1] between given edges.
The smoothing is calculated as specified in the OpenGL Shading Language specification. edge1 must be less than edge2. Value of the function is 0 if t <= edge1 and 1 if t >= edge2. If edge1 < t < edge2, the value is interpolated smoothly between edge1 and edge2 in a way that the derivative of the function is f'(edge1) == f'(edge2) == 0.
