Detailed Description

template<typename Index_, typename Data_>
class knncolle::SimpleMatrix< Index_, Data_ >

Simple wrapper for an in-memory matrix.

This defines a simple column-major matrix of observations where the columns are observations and the rows are dimensions. It is compatible with the compile-time interface described in MockMatrix.

Template Parameters

Index_	Integer type of the observation indices.
Data_	Numeric type of the data.

Constructor & Destructor Documentation

SimpleMatrix()

template<typename Index_ , typename Data_ >

knncolle::SimpleMatrix< Index_, Data_ >::SimpleMatrix ( std::size_t num_dimensions, Index_ num_observations, const Data_ * data )

inline

Parameters

	num_dimensions	Number of dimensions.
	num_observations	Number of observations.
[in]	data	Pointer to an array of length num_dim * num_obs, containing a column-major matrix of observation data. It is expected that the array will not be deallocated during the lifetime of this SimpleMatrix instance.
