Hi guys,
I am getting a run-time assert when calling ::row on a Matrix<double,
Dynamic, Dynamic, 1, 3, 3>.
The assert is caused by the check in lines 291-293 of Block.h and the
issue is that BlockRows!=XprType::RowsAtCompileTime but
BlockRows==XprType::MaxRowsAtCompileTime. Changing the assert to
eigen_assert( (i>=0) && (
((BlockRows==1) &&
(BlockCols==XprType::ColsAtCompileTime||BlockCols==XprType::MaxColsAtCompileTime)
&& i<xpr.rows())
||((BlockRows==XprType::RowsAtCompileTime||BlockRows==XprType::MaxRowsAtCompileTime)
&& (BlockCols==1) && i<xpr.cols())));
fixes the problem.
Does anybody see an issue with doing this globally in Block.h?
