#	Name	Type	Description
1	Value	const double
2	Index	int
3	Len	int

Remarks:

An exception is raised if array borders are overrun or underrun.

Multiply each element of Vec with Value.

#	Name	Type	Description
1	Vec	TMtxVec *
2	Value	const double

Remarks:

Store the result in the calling object. Size and TSparseMtx::Complex properties of the calling object are adjusted automatically.

Declared in Dew::Math::TMtxVec · Dew.Math/AbstractMtxVec.h · Cross-compiler

Overload 6: TMtxVec Mul(TMtxVec Vec, const TCplx &Value);

Multiply each element of Vec with complex Value.

#	Name	Type	Description
1	Vec	TMtxVec *
2	Value	const TCplx &

Remarks:

Store the result in the calling object. Size of the calling object is set automatically. TSparseMtx::Complex property of the calling object is set to True.

Declared in Dew::Math::TMtxVec · Dew.Math/AbstractMtxVec.h · Cross-compiler

Overload 7: TMtxVec Mul(TMtxVec Vec, const double Value, int VecIndex, int Index, int Len);

Multiply Vec elements [VecIndex]..[VecIndex+Len-1] with Value.

#	Name	Type	Description
1	Vec	TMtxVec *
2	Value	const double
3	VecIndex	int
4	Index	int
5	Len	int

Remarks:

Store the result in calling object elements [Index]..[Index+Len-1]. Size of the calling object is not changed. An exception is raised if array borders are overrun or underrun. TSparseMtx::Complex propertiy of the calling object is set implicitly.

Declared in Dew::Math::TMtxVec · Dew.Math/AbstractMtxVec.h · Cross-compiler

Overload 8: TMtxVec Mul(TMtxVec Vec, const TCplx &Value, int VecIndex, int Index, int Len);

Multiply Vec elements [VecIndex]..[VecIndex+Len-1] with complex Value.

#	Name	Type	Description
1	Vec	TMtxVec *
2	Value	const TCplx &
3	VecIndex	int
4	Index	int
5	Len	int

Remarks:

Store the result in calling object elements [Index]..[Index+Len-1]. Size of the calling object is not changed. An exception is raised if array borders are overrun or underrun. TSparseMtx::Complex propertiy of the calling object is set to True.

Declared in Dew::Math::TMtxVec · Dew.Math/AbstractMtxVec.h · Cross-compiler

Overload 9: void Mul(TSparseMtx C, TSparseMtx B, int MaxNonZeroCount = 10000000);

Multiply two sparse matrices (matrix multiplication).

#	Name	Type	Description
1	C	TSparseMtx *
2	B	TSparseMtx *
3	MaxNonZeroCount = 10000000	int

Remarks:

Multiply sparse matrices A and B and place the result in the calling matrix. Because the resulting matrix can be much less sparse, the memory requirements can increase beyond the available system memory. This method will raise an exception, if the requested memory size will exceed the value of MaxNonZeroCount.
