| template<typename T1 > | |
| arma_inline const Op< T1, op_sum > | sum (const Base< typename T1::elem_type, T1 > &X, const uword dim=0) |
| 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. | |
| template<typename eT > | |
| arma_warn_unused eT | sum (const Row< eT > &X) |
| Immediate 'sum all values' operation for a row vector. | |
| template<typename eT > | |
| arma_warn_unused eT | sum (const Col< eT > &X) |
| Immediate 'sum all values' operation for a column vector. | |
| template<typename T1 > | |
| arma_warn_unused T1::elem_type | sum (const Op< T1, op_sum > &in) |
| Immediate 'sum all values' operation, invoked, for example, by: sum(sum(A)) | |

| arma_warn_unused eT | sum (const subview_row< eT > &X) |
| sum all values of a subview_row | |
