Detailed Description

This class stores a dense matrix and allows it to be accessed as a collection of vertical blocks. The dimensions of the blocks are provided when constructing this class.

This class also has three parameters that can be changed after construction that change the apparent view of the matrix without any reallocation or data copying. firstBlock() determines the block that has index 0 for all operations (except for re-setting firstBlock()). rowStart() determines the apparent first row of the matrix for all operations (except for setting rowStart() and rowEnd()). rowEnd() determines the apparent exclusive (one-past-the-last) last row for all operations. To include all rows, rowEnd() should be set to the number of rows in the matrix (i.e. one after the last true row index).

◆ LikeActiveViewOf() [1/2]

VerticalBlockMatrix gtsam::VerticalBlockMatrix::LikeActiveViewOf	(	const SymmetricBlockMatrix &	rhs,
		DenseIndex	height
	)

static

Copy the block structure, but do not copy the matrix data. If blockStart() has been modified, this copies the structure of the corresponding matrix view. In the destination VerticalBlockMatrix, blockStart() will be 0.

Definition at line 39 of file VerticalBlockMatrix.cpp.

◆ LikeActiveViewOf() [2/2]

VerticalBlockMatrix gtsam::VerticalBlockMatrix::LikeActiveViewOf ( const VerticalBlockMatrix & rhs )

static

Copy the block structure and resize the underlying matrix, but do not copy the matrix data. If blockStart(), rowStart(), and/or rowEnd() have been modified, this copies the structure of the corresponding matrix view. In the destination VerticalBlockView, blockStart() and rowStart() will thus be 0, rowEnd() will be cols() of the source VerticalBlockView, and the underlying matrix will be the size of the view of the source matrix.

Definition at line 25 of file VerticalBlockMatrix.cpp.
