Functions

template<typename T1 >
const Op< T1, op_minmin (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. For dim = 1, the maximum value of each row is found. The default is dim = 0. NOTE: This function works differently than in Matlab/Octave.
template<typename eT >
eT min (const Row< eT > &A)
 Immediate 'find the minimum value in a row vector' operation.
template<typename eT >
eT min (const Col< eT > &A)
 Immediate 'find the minimum value in a column vector'.
template<typename T1 >
T1::elem_type min (const Op< T1, op_min > &in)
 Immediate 'find minimum value' operation, invoked, for example, by: min(min(A)).
