Detailed Description

template<typename _ArgType, int _Rows = _ArgType::RowsAtCompileTime, int _Cols = _ArgType::ColsAtCompileTime, bool _allRows = false, bool _allCols = false>
class Eigen::MatrixBlockView< _ArgType, _Rows, _Cols, _allRows, _allCols >

A view of an Eigen matrix.

Instances of MatrixBlockView are easily built from a MatrixBlocks object.

As of the date of this documentation, this class does not support all operations on matrices. See tests/matrix-view.cc for a list of supported features.

Although it is usually not useful to iterate over the blocks, it is possible to do it as follows:

MatrixBlockView view = ...;
for (MatrixBlockView::block_iterator block (view); block.valid(); ++block)
{
  // Access the current block
  view._block(block); // Returns an Eigen::Block object.
  // For the current block
  block.ri() // row, input
  block.ci() // col, input
  block.ro() // row, output
  block.co() // col, output
  block.rs() // number of rows
  block.cs() // number of cols
}
