Functions

template<typename T1 >
const Op< T1, op_sumsum (const Base< typename T1::elem_type, T1 > &X, const u32 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 >
eT sum (const Row< eT > &X)
 Immediate 'sum all values' operation for a row vector.
template<typename eT >
eT sum (const Col< eT > &X)
 Immediate 'sum all values' operation for a column vector.
template<typename T1 >
T1::elem_type sum (const Op< T1, op_sum > &in)
 Immediate 'sum all values' operation, invoked, for example, by: sum(sum(A)).
template<typename T1 >
const Op< Op< T1, op_sum >
, op_sum
sum (const Op< T1, op_sum > &in, const u32 dim)
template<typename eT >
eT sum (const subview_row< eT > &X)
 sum all values of a subview_row
template<typename eT >
eT sum (const subview_col< eT > &X)
 sum all values of a subview_col
template<typename eT >
eT sum (const diagview< eT > &X)
 sum all values of a diagview
