Detailed Description

A constant view of a Vector.

Together with the derived class VectorView this contains the main implementation of a Vector. The class Vector is just a special case of a VectorView which also allocates storage.

Destructor.

ConstVectorView() [3/6]

A special constructor, which allows to make a ConstVectorView from a scalar.

ConstVectorView() [4/6]

ConstVectorView::ConstVectorView ( )

ConstVectorView() [5/6]

ConstVectorView::ConstVectorView ( Numeric *  data, const Range &  range  )

protected

Explicit constructor.

This one is used by Vector to initialize its own VectorView part.

Definition at line 91 of file matpackI.cc.

ConstVectorView() [6/6]

ConstVectorView::ConstVectorView ( Numeric *  data, const Range &  p, const Range &  n  )

protected

Recursive constructor.

This is used to construct sub ranges from sub ranges. That means that the new range has to be interpreted relative to the original range. The new range may contain -1 for the extent which acts as a joker. However, the used Range constructor converts this to an explicit range, consistent with the original Range.

Parameters

*data	The actual data.
p	Previous range.
n	New Range.

get_c_array()

Numeric * ConstVectorView::get_c_array ( ) const

inlinenoexcept

Conversion to plain C-array, const-version.

This function returns a pointer to the raw data. It fails if the VectorView is not pointing to the beginning of a Vector or the stride is not 1 because the caller expects to get a C array with continuous data.

nelem()

Index ConstVectorView::nelem ( ) const

inlinenoexcept

Returns the number of elements.

The names ‘size’ and ‘length’ are already used by STL functions returning size_t. To avoid confusion we choose the name ‘nelem’. This is also more consistent with ‘nrow’ and ‘ncol’ for matrices.

The value range of long, which is used to store the index is on a PC from -2147483648 to 2147483647. This means that a 15GB large array of float can be addressed with this index. So the extra bit that size_t has compared to long is not needed.

diagonalize

void diagonalize ( MatrixView  , VectorView  , VectorView  , ConstMatrixView    )

friend

Matrix Diagonalization.

Return P and W from A in the statement diag(P^-1*A*P)-W == 0. The real function will require some manipulation if the eigenvalues are imaginary.

The real version returns WR and WI as returned by dgeev. The complex version just returns W.

The function makes many copies and is thereby not fast. There are no tests on the condition of the returned matrix, so nan and inf can occur.

Parameters

[out]	P	The right eigenvectors.
[out]	WR	The real eigenvalues.
[out]	WI	The imaginary eigenvalues.
[in]	A	The matrix to diagonalize.

LU backsubstitution.

Solves a set of linear equations Ax=b. It is neccessairy to do a L decomposition using the function ludcp before using this function. The backsubstitution is in-place, i.e. x and b may be the same vector.

Parameters

x	Output: Solution vector of the equation system.
LU	Input: LU decomposition of the matrix (output of function ludcp).
b	Input: Right-hand-side vector of equation system.
indx	Input: Pivoting information (output of function ludcp).

mult [1/2]

void mult ( VectorView  , const ConstMatrixView &  , const ConstVectorView &    )

Matrix-Vector Multiplication.

Computes the Matrix-Vector product y = M * x, for a m times n matrix M, a length-m vector y and a length-n vector x.

The product is computed using the dgemv_ routine from the BLAS library if the matrix is contiguous in memory. If this is not the case, the mult_general method is used to compute the product.

No memory is allocated for the computation and the matrix and vector views may not overlap.

Parameters

[out]	y	The length-m VectorView where the result is stored.
[in]	M	Reference to the m-times-n ConstMatrixView holding the matrix M.
[in]	x	Reference to the length-n ConstVectorView holding the vector x.

mult [2/2]

void mult ( VectorView  , const Sparse &  , ConstVectorView    )

friend

Sparse matrix - Vector multiplication.

This calculates the product

y = M*x, where M is sparse.

Output comes first!

Dimensions of y, M, and x must match. No memory reallocation takes place, only the data is copied.

Parameters

y	Output: The multiplication result.
M	Matrix for multiplication (sparse).
x	Vector for multiplication.

mult_general

void mult_general ( VectorView  y, const ConstMatrixView &  M, const ConstVectorView &  x  )

friend

Matrix Vector multiplication.

y = M*x. Note that the order is different from MTL, output comes first! Dimensions of y, M, and x must match. No memory reallocation takes place, only the data is copied. Using this function on overlapping Matrix and VectorViews belonging to the same Matrix will lead to unpredictable results.

The implementation here is different from the other multiplication routines. It does not use iterators but a more drastic approach to gain maximum performance.

operator*

Numeric operator* ( const ConstVectorView &  a, const ConstVectorView &  b  )

friend

Scalar product.

The two vectors may be identical.

poly_root_solve

int poly_root_solve ( Matrix &  roots, Vector &  coeffs  )

friend

transpose_mult

void transpose_mult ( VectorView  , const Sparse &  , ConstVectorView    )

friend

Sparse matrix - Vector multiplication.

This calculates the product

y = M*x, where M is sparse.

Output comes first!

Dimensions of y, M, and x must match. No memory reallocation takes place, only the data is copied.

Parameters

y	Output: The multiplication result.
M	Matrix for multiplication (sparse).
x	Vector for multiplication.
