Hi,
So i would like to implement a function that get a vector as input lets :
g=[g1, g2, g3]
and return a matrix that contain a sum of pairs: so for g , the output matrix G contain 9 elements the G(i,j)=g(i)+g(j)
The problem is that g will be very large vector.
Does anyone know an efficient way to do that with sparse matrices
Thanks
