VectorInt.ThreshAbsLT Method

Overload List

#	Signature	Description
1	TMtxVecInt ThreshAbsLT(TMtxVecInt Src, Int32 Value)	Perform threshold operation on all Src object values.
	└ indexed: TMtxVecInt ThreshAbsLT(TMtxVecInt Vec, Int32 Value, Int32 VecIndex, Int32 Index, Int32 Len)
2	TMtxVecInt ThreshAbsLT(Int32 Value)	Threshold top and bottom centered around zero.
	└ indexed: TMtxVecInt ThreshAbsLT(Int32 Value, Int32 Index, Int32 Len)

Overload 1: TMtxVecInt ThreshAbsLT(TMtxVecInt Src, Int32 Value)

Perform threshold operation on all Src object values.

#	Name	Type	Description
1	Src	TMtxVecInt	source TVecInt or TMtxInt
2	Value	Int32

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

Remarks:

Store the results in calling object. Size and Dew.Math.VectorInt.IntPrecision properties of the calling object are adjusted automatically.

Indexed: TMtxVecInt ThreshAbsLT(TMtxVecInt Vec, Int32 Value, Int32 VecIndex, Int32 Index, Int32 Len)

Perform a threshold operation Vec elements [VecIndex]..[VecIndex+Len-1].

#	Name	Type	Description
1	Vec	TMtxVecInt	source TVecInt or TMtxInt
2	Value	Int32
3	VecIndex	Int32
4	Index	Int32	start index
5	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.VectorInt.IntPrecision 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.

Overload 2: TMtxVecInt ThreshAbsLT(Int32 Value)

Threshold top and bottom centered around zero.

#	Name	Type	Description
1	Value	Int32

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

Remarks:

Perform threshold operation on all calling object values. The Value parameter is an upper bound for threshold operation. All values smaller than Value will be replaced with Value and all values bigger than -Value will be replaced with -Value. The comparison checks if abs(Values[i]) < Value.

Examples

using Dew.Math;
using Dew.Math.Units;

namespace Dew.Examples
{
    void Example()
    {
        TVecInt a;
        MtxVecInt.CreateIt(out a);
        try
        {
            a.SetIt(new int[] {2,-1,3,4});
            a.ThreshAbsLT(2); // a = [2,-2,3,4]
        }
        finally
        {
            MtxVec.FreeIt(ref a);
        }
    }
}

Indexed: TMtxVecInt ThreshAbsLT(Int32 Value, Int32 Index, Int32 Len)

Perfrom the threshold operation on calling object values [Index]..[Index+Len-1].

#	Name	Type	Description
1	Value	Int32
2	Index	Int32	start index
3	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.
