Constructor & Destructor Documentation

template<class __value_type, class __memory_space_type, class __index_type = unsigned int>

cuv::cuda_array< __value_type, __memory_space_type, __index_type >::cuda_array ( const index_type &  height, const index_type &  width, const index_type &  depth = 1, const unsigned int  dim = 1  )

inline

Construct uninitialized memory with given width/height.

Parameters

dim	dimension of a single point in the array (can be 1 or 4)

when type is float and dim=1 then the cudaArray is float

when type is float and dim=4 then the cudaArray is float4

Definition at line 78 of file cuda_array.hpp.

template<class S >

cuv::cuda_array< __value_type, __memory_space_type, __index_type >::cuda_array ( const tensor< value_type, S, row_major > &  src, const unsigned int  dim = 1  )

inline

Construct by copying.

Parameters

dim	dimension of a single point in the array (can be 1 or 4)

when type is float and dim=1 then the cudaArray is float

when type is float and dim=4 then the cudaArray is float4

Parameters

dim	construct by copying a dense matrix
