//! Delayed sum of elements of a matrix along a specified dimension (either rows or columns). //! The result is stored in a dense matrix that has either one column or one row. //! For dim = 0, find the sum of each column. //! For dim = 1, find the sum of each row. //! The default is dim = 0. //! NOTE: this function works differently than in Matlab/Octave. | |
