New Post: How to apply operation over vector from each row/column of a matrix?

Hi Federico,

I don't fully understand yet what the operation should do. What does Functions.Sum(v, Axis.Rows) do and how does it relate to ones * diag(v), exactly?

Maybe you're looking for FoldRows(f,state) which applies a binary function to each row vector of the matrix and a state vector (where the result becomes the state for the next row)? See also "Enumerators and Higher Order Functions" in Matrices and Vectors.

Thanks,
Christoph
