template<typename T1 > | |
arma_inline const Op< T1, op_min > | min (const Base< typename T1::elem_type, T1 > &X, const u32 dim=0) |
Delayed 'minimum values' operation. The dimension, along which the minima are found, is set via 'dim'. For dim = 0, the maximum value of each column is found (i.e. searches by traversing across rows). For dim = 1, the maximum value of each row is found (i.e. searches by traversing across columns). The default is dim = 0. NOTE: This function works differently than in Matlab/Octave. | |
template<typename eT > | |
arma_warn_unused eT | min (const Row< eT > &A) |
Immediate 'find the minimum value in a row vector' operation. | |
template<typename eT > | |
arma_warn_unused eT | min (const Col< eT > &A) |
Immediate 'find the minimum value in a column vector'. | |
template<typename T1 > | |
arma_warn_unused T1::elem_type | min (const Op< T1, op_min > &in) |
Immediate 'find minimum value' operation, invoked, for example, by: min(min(A)). | |
