Detailed Description

A read-only view of a column-oriented matrix.

Note:: Implicit promotion of a MatView to a ConstMatView is forbidden, because it violates the expectation that ConstMatView points to a matrix that doesn't change during the computation.

Constructor & Destructor Documentation

template<class Ordinal, class Scalar>

TSQR::ConstMatView< Ordinal, Scalar >::ConstMatView	(	const Ordinal	num_rows,
		const Ordinal	num_cols,
		const Scalar *const	A,
		const Ordinal	leading_dim
	)		`[inline]`

Note:: g++ with -Wall wants A_ to be initialized after lda_, otherwise it emits a compiler warning.

template<class Ordinal, class Scalar>

ConstMatView TSQR::ConstMatView< Ordinal, Scalar >::rowBlock	(	const Ordinal	firstRow,
		const Ordinal	lastRow
	)		const `[inline]`

Return a "row block" (submatrix of consecutive rows in the inclusive range [firstRow,lastRow]).

Definition at line 475 of file Tsqr_MatView.hpp.

template<class Ordinal, class Scalar>

ConstMatView TSQR::ConstMatView< Ordinal, Scalar >::split_top	(	const Ordinal	nrows_top,
		const bool	b_contiguous_blocks = `false`
	)		`[inline]`

Split off and return the top block. Modify *this to be the "rest" of the matrix.

Note:: Only use this method to split off a single cache block. It breaks if you try to use it otherwise.

Parameters:

nrows_top	[in] Number of rows in the top block (which this method returns)
b_contiguous_blocks	[in] Whether or not the entries of the top block are stored contiguously in *this. The default is no (false).

Returns:: The top block of nrows_top rows. Data is a shallow copy of the data in *this.

template<class Ordinal, class Scalar>

ConstMatView TSQR::ConstMatView< Ordinal, Scalar >::split_bottom	(	const Ordinal	nrows_bottom,
		const bool	b_contiguous_blocks = `false`
	)		`[inline]`

Split off and return the bottom block. Modify *this to be the "rest" of the matrix.
