Question about the usage of self.M in ‘QuadraticSpline‘ #3
Description
Hello, Li.
I have read your published paper and code, and I think it's excellent work.
My question is about the variable self.M = torch.kron(self.BC, self.BC) in class QuadraticSpline.
It seems that this variable occupies a large amount of memory, and I often encounter "out of memory" errors during execution.
However, I am not sure about the purpose of self.Mand I couldn't find its usage in other files.
Thank you for open-sourcing this code, which has been very helpful to me. I would be very grateful if you could reply.
