Vectorizing second derivative expression for Lagrange polynomials
显示 更早的评论
Hi everyone,
I am trying to vectorize the following expression for the second derivative of the jth Lagrange polynomial at the ith construction point.
I have been able to vectorize the expression for the innermost product, but I am running into issues when trying to vectorize the outer sums.
I would greatly appreciate any help in vectorizing this expression:
