TMtx.Erfc Method — Dew Math

Overload List

#	Signature	Description
1	TMtxVec Erfc	Complementary error functon of values.
	└ indexed: TMtxVec Erfc(Int32 Index, Int32 Len)
2	TMtxVec Erfc(TMtxVec Src)	Calculates the complementary error function value for all Src object values.
	└ indexed: TMtxVec Erfc(TMtxVec Src, Int32 SrcIndex, Int32 Index, Int32 Len)

Overload 1: TMtxVec Erfc

Complementary error functon of values.

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

Remarks:

Calculates the complementary error function value for all object values in-place.

Examples

Matrix a = new Matrix();
a.SetIt(2, 2, false, new double[] { 0.0, 0.5, 1.0, 2.0 });
a.Erfc();
Matrix expected = new Matrix();
expected.SetIt(2, 2, false, new double[] { 1.0, 0.479500122186953, 0.157299207050285, 0.00467773498104727 });
if (!a.IsEqual(expected, 1e-10, TCompare.cmpAbsolute))
    throw new Exception("Matrix.Erfc: mismatch");

Indexed: TMtxVec Erfc(Int32 Index, Int32 Len)

Calculates the complementary error function value for calling object elements [Index]..[Index+Len-1] in-place.

#	Name	Type	Description
1	Index	Int32	start index
2	Len	Int32	element count

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

Remarks:

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

Overload 2: TMtxVec Erfc(TMtxVec Src)

Calculates the complementary error function value for all Src object values.

#	Name	Type	Description
1	Src	TMtxVec	source TVec or TMtx

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

Remarks:

Stores the result in calling object. Size and Dew.Math.TMtxVec.Complex properties of calling object are adjusted automatically.

Examples

Matrix a = new Matrix();
Matrix x = new Matrix();
x.SetIt(2, 2, false, new double[] { 0.0, 0.5, 1.0, 2.0 });
a.Erfc(x);
Matrix expected = new Matrix();
expected.SetIt(2, 2, false, new double[] { 1.0, 0.479500122186953, 0.157299207050285, 0.00467773498104727 });
if (!a.IsEqual(expected, 1e-10, TCompare.cmpAbsolute))
    throw new Exception("Matrix.Erfc: mismatch");

Indexed: TMtxVec Erfc(TMtxVec Src, Int32 SrcIndex, Int32 Index, Int32 Len)

Calculates the complementary error function value for Src object elements [SrcIndex]..[SrcIndex+Len-1].

#	Name	Type	Description
1	Src	TMtxVec	source TVec or TMtx
2	SrcIndex	Int32	source start index
3	Index	Int32	start index
4	Len	Int32	element count

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

Remarks:

Stores the result in calling object elements [Index]..[Index+Len-1]. An exception is raised if array borders are overrun or underrun.
