| template<typename T1 > | |
| arma_inline const Op< T1, op_prod > | prod (const Base< typename T1::elem_type, T1 > &X, const uword dim=0) |
| Delayed product 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 (i.e. traverse across rows) For dim = 1, find the sum of each row (i.e. traverse across columns) The default is dim = 0. NOTE: this function works differently than in Matlab/Octave. | |
