Method Description
AddRow ( int iTargetRow, int iSecondRow, Fraction iMultiple ) : void

The function adds two rows for current MatrixClass object It performs the following calculation: iTargetRow = iTargetRow + iMultiple*iSecondRow
Adjoint ( int b ) : MatrixClass

The function returns the adjoint of the current MatrixClass
Concatenate ( MatrixClass MatrixClass1, MatrixClass MatrixClass2 ) : MatrixClass

The function concatenates the two given matrices column-wise it can be helpful in a equation solver class where the augmented MatrixClass is obtained by concatenation
Determinent ( ) : Fraction

The function returns the determinent of the current MatrixClass object as Fraction It computes the determinent in the traditional way (i.e. using minors) It can be much slower(due to recursion) if the given MatrixClass has order greater than 6 Try using DeterminentFast() function if the order of MatrixClass is greater than 6
