Declaration	Notes
void Product( const double **m1 , long rows1 ,long cols1 , const double **m2 , long rows2 , long cols2 , double ***m3, long *rows3 , long *cols3);	Computes product of two matrices. Product returned in in/out parameter m3. Product size in rows3,cols3
void __fastcall Sum( const double **m1 , long rows1 ,long cols1 , const double **m2 , long rows2 , long cols2 , double ***m3 );	Sum of two matrices. Return values as above
void __fastcall Difference( const double **m1 , long rows1 ,long cols1 , const double **m2 , long rows2 , long cols2 , double ***m3 );	Difference of two matrices. Return values same as Product
double __fastcall double TraceOf(const double **m1 , long rows , long cols );	Computes TraceOf matrix. Returned as double
void __fastcall Transpose( const double **m1 , long rows , long cols , double ***transposed);	Transposes matrix. Returned in transposed

         Events

Declaration	Notes
TNotifyEvent OnProductError	Event for product error
TNotifyEvent OnDifferenceError	Event for difference error
TNotifyEvent OnSumError	Event for sum error
TNotifyEvent OnTraceOfError	Event for TraceOf error
TNotifyEvent OnTransposeError	Event for Transpose error

Notes :

All methods work on matrices of type double. A template is enclosed for operation on other data types with same methods.
