TSparseMtx.ThresholdGT_LT Method

Overload List

#	Signature	Description
1	TMtxVec ThresholdGT_LT(TMtxVec Vec, Double GTLevel, Double GTValue, Double LTLevel, Double LTValue)	Perform "greater than and less than" threshold operation on all Vec object values.
	└ indexed: TMtxVec ThresholdGT_LT(TMtxVec Vec, Double GTLevel, Double GTValue, Double LTLevel, Double LTValue, Int32 VecIndex, Int32 Index, Int32 Len)
2	TMtxVec ThresholdGT_LT(Double GTLevel, Double GTValue, Double LTLevel, Double LTValue)	Threshold greater than and less than operation.
	└ indexed: TMtxVec ThresholdGT_LT(Double GTLevel, Double GTValue, Double LTLevel, Double LTValue, Int32 Index, Int32 Len)

Overload 1: TMtxVec ThresholdGT_LT(TMtxVec Vec, Double GTLevel, Double GTValue, Double LTLevel, Double LTValue)

Perform "greater than and less than" threshold operation on all Vec object values.

#	Name	Type	Description
1	Vec	TMtxVec	source TVec or TMtx
2	GTLevel	Double	scalar
3	GTValue	Double	scalar
4	LTLevel	Double	scalar
5	LTValue	Double	scalar

Result: stored in self (calling object), returns self for chaining

Remarks:

Store the results in calling object. Size and Dew.Math.TMtxVec.Complex properties of the calling object are adjusted automatically. An exception will be raised if Vec object contains complex numbers.

Indexed: TMtxVec ThresholdGT_LT(TMtxVec Vec, Double GTLevel, Double GTValue, Double LTLevel, Double LTValue, Int32 VecIndex, Int32 Index, Int32 Len)

Perform "greater than and less than" threshold operation on Vec elements from range [VecIndex]..[VecIndex+Len-1].

#	Name	Type	Description
1	Vec	TMtxVec	source TVec or TMtx
2	GTLevel	Double	scalar
3	GTValue	Double	scalar
4	LTLevel	Double	scalar
5	LTValue	Double	scalar
6	VecIndex	Int32
7	Index	Int32	start index
8	Len	Int32	element count

Result: stored in self (calling object), returns self for chaining

Remarks:

Store the results in the calling object elements [Index]..[Index+Len-1]. Size and Dew.Math.TMtxVec.Complex properties of the calling object must be set explicitly. An exception is raised if Dew.Math.TMtxVecBase.ConditionCheck is true and array borders are overrun/underrun. An exception will be raised if Vec object or the calling object contain complex numbers.

Overload 2: TMtxVec ThresholdGT_LT(Double GTLevel, Double GTValue, Double LTLevel, Double LTValue)

Threshold greater than and less than operation.

#	Name	Type	Description
1	GTLevel	Double	scalar
2	GTValue	Double	scalar
3	LTLevel	Double	scalar
4	LTValue	Double	scalar

Result: stored in self (calling object), returns self for chaining

Remarks:

Perform operation on all calling object values. The LTValue parameter is an lower bound for threshold operation. The GTValue parameter is an upper bound for threshold operation. All values less than LTLevel will be replaced with LTValue. All values bigger than GTLevel will be replaced with GTValue. Operation is available only for not Complex values.

Examples

Matrix a;
a.SetIt(1,2,true,new double[] {2,0.1,3,4});
a.ThresholdGT_LT(2.3,3.4,1,0.5); // a = new double[] {2,0.5,3.4,3.4}

Indexed: TMtxVec ThresholdGT_LT(Double GTLevel, Double GTValue, Double LTLevel, Double LTValue, Int32 Index, Int32 Len)

Perfrom "greater than and less than" threshold operation on the calling object values in range [Index]..[Index+Len-1].

#	Name	Type	Description
1	GTLevel	Double	scalar
2	GTValue	Double	scalar
3	LTLevel	Double	scalar
4	LTValue	Double	scalar
5	Index	Int32	start index
6	Len	Int32	element count

Result: stored in self (calling object), returns self for chaining

Remarks:

An exception is raised if array borders are overrun/underrun. An exception will be raised if the calling object contains complex numbers.
