Header file for the MatAbsExpr base class.
Compile time check whether the given type is a matrix absolute value expression template.This type trait class tests whether or not the given type Type is a matrix absolute value expression template. In order to qualify as a valid matrix absolute value expression template, the given type has to derive (publicly or privately) from the MatAbsExpr base class. In case the given type is a valid matrix absolute value expression template, the value member enumeration is set to 1, the nested type definition Type is TrueType, and the class derives from TrueType. Otherwise value is set to 0, Type is FalseType, and the class derives from FalseType.
