Bivariate(2D) Chebyshev implementation need to be checked because it doesn't work
显示 更早的评论
Hello,
I have to implement the 2D-Chebyshev interpolation for a random function on a random rectangle.
The Interpolation polynomial is :
with the coeff
where the '' means that the first and the last summand are halved.
x_k and y_k are the chebyshev nodes.
T_i is the first degree chebyshev polynomial.
I don't know why code doesn't work.
Could someone help me. Here is my code
