Detailed Description

A constant view of a Matrix.

This, together with the derived class MatrixView, contains the main implementation of a Matrix. It defines the concepts of MatrixView. Plus additionally the recursive subrange operator, which makes it possible to create a MatrixView from a subrange of a MatrixView.

The class Matrix is just a special case of a MatrixView which also allocates storage.

ConstMatrixView::ConstMatrixView	(	Numeric *	data,

protected

Recursive constructor.

This is used to construct SubMatrices from SubMatrices. That means that the new ranges have to be interpreted relative to the original ranges.

The new ranges 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.
pr	Previous range.
pc	Previous range.
nr	New Range.
nc	New Range.

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.

Parameters

Matrix-Matrix Multiplication.

Performs the matrix multiplication A = B * C. The dimensions must match, i.e. A must be a m times n matrix, B a m times k matrix and C a k times c matrix. No memory reallocation takes place, only the data is copied. Using this function on overlapping MatrixViews belonging to the same Matrix will lead to unpredictable results. In particular, this means that A and B must not be the same matrix!

If the memory layout allows it, the multiplication is performed using BLAS' _dgemm, which leads to a significant speed up of the operation. To be compatible with BLAS the matrix views A, B and C must satisfy:

A must have column or row stride 1
B must have column or row stride 1
C must have column stride 1

That means that A and B can be ConstMatrixView objects corresponding to transposed/non-transposed submatrices of a matrix, that are continuous along their first/second dimension. C must correspond to a non-transposed submatrix of a matrix, that is continuous along its second dimension.

Parameters

[in,out]	A	The matrix A, that will hold the result of the multiplication.
[in]	B	The matrix B
[in]	C	The matrix C

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.

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.
