Constructor & Destructor Documentation

theplu::yat::classifier::DataLookup1D::DataLookup1D ( const MatrixLookup m,
const size_t  index,
const bool  row_vector 
)

Constructor.

Parameters
mMatrixLookup to look into
row_vectorif true DataLookup1D is looking into a row of MatrixLookup, otherwise looking into a column.
indexwhich row/column to look into.
theplu::yat::classifier::DataLookup1D::DataLookup1D ( const DataLookup1D )

Copy constructor

theplu::yat::classifier::DataLookup1D::DataLookup1D ( const size_t  size,
const double  value = 0 
)

Construct DataLookup1D that owns its underlying matrix. Object has size @ size and all its element is equal to value.

theplu::yat::classifier::DataLookup1D::DataLookup1D ( const utility::VectorBase vec,
const std::vector< size_t > &  index 
)

Create general view from utility::VectorBase.

Constructor creates a proper MatrixLookup that object can view into. Object is owner of this underlying MatrixLookup. Object fulfills $ x(i) = vec(index(i)) $

theplu::yat::classifier::DataLookup1D::DataLookup1D ( const utility::VectorBase vec)

Create general view from utility::VectorBase.

Constructor creates a proper MatrixLookup that object can view into. Object is owner of this underlying MatrixLookup. Object fulfills $ x(i) = vec(i) $

Converts a DataLookup1D to a utility::vector

std::ostream & operator<< ( std::ostream &  s,
const DataLookup1D v 
)
related

The output operator for DataLookup1D.

Elements are separated by the character from the omanip fill. The following example will write the elements separated by tab.

char prev=s.fill('\t'); 
s << v;
s.fill(prev);
