template<typename ConditionMatrixType, typename ThenMatrixType, typename ElseMatrixType>
class Eigen::Select< ConditionMatrixType, ThenMatrixType, ElseMatrixType >

Expression of a coefficient wise version of the C++ ternary operator ?:

Parameters

ConditionMatrixType	the type of the condition expression which must be a boolean matrix
ThenMatrixType	the type of the then expression
ElseMatrixType	the type of the else expression

This class represents an expression of a coefficient wise version of the C++ ternary operator ?:. It is the return type of DenseBase::select() and most of the time this is the only way it is used.
