Structure for a dense 3D Array

Tensor3Iterator Explanation

dense rowmajor 3D array

Constructor(s), Destructors(s) Tensor3() default constructor explicit Tensor3( Index const& n ) build a matrix Tensor3( Index const& n, Index const& p ) build a matrix, with . Tensor3( Index const& n, Index const& p, Index const& q ) build a matrix

operations on profil size_t size() const get size void resize( size_t const n ) resize void resize( size_t const n, size_t const p ) resize void resize( size_t const n, size_t const p, size_t const q ) resize

Access to element Index rows() const get number of rows Index cols() const get number of cols Index depth() const get depth Index n() const get number of rows Index p() const get number of cols Index q() const get number of cols Index firstInRow( Index const i ) const get first element in the i-th row Index firstInCol( Index const j ) const get first element in the j-th column Index firstInDepth( Index const k ) const get first element in the k-th depth Index lastInRow( Index const i ) const get last element in the i-th row Index lastInCol( Index const j ) const get last element in the j-th column Index lastInDepth( Index const k ) const get last element in the k-th column Bool isDepthMajor() true if the storage is by depth first and then by rows and then by column Bool isRowMajor() true if the storage is row major (C-like) Bool isColumnMajor() true if the storage is column major (fortran-like) T_value& get( T_value* const data, Index const i, Index const j, Index const k ) set value T_value get( T_value const* const data, Index const i, Index const j, Index const k ) const get value T_value& get_fast( T_value* const data, Index const i, Index const j, Index const k ) set value fast T_value get_fast( T_value const* const data, Index const i, Index const j, Index const k ) const get value fast Bool isFactored() const true if matrix is factored void setIsFactored() set isFactored to true void setIsNotFactored() set isFactored to false Index offset() const map(MinIndex,MinIndex,MinIndex) void computeOffset() compute offset

size_t my_data_length

number of elements asked by user

UInt my_offset

Bool my_matrix_is_factored

is matrix factored ?

Index map( Index const i, Index const j, Index const k ) const

map(i,j,k) find the position in the data array

Index map_fast( Index const i, Index const j, Index const k ) const

same as map(i,j) but without any control
