TSparseMtx.ArcSinh Method

Overload List

#	Signature	Description
1	TMtxVec ArcSinh	Inverse hyperbolic sine.
	└ indexed: TMtxVec ArcSinh(Int32 Index, Int32 Len)
2	TMtxVec ArcSinh(TMtxVec X)	Calculate the inverse hyperbolic sine for all X object elements.
	└ indexed: TMtxVec ArcSinh(TMtxVec X, Int32 XIndex, Int32 Index, Int32 Len)

Overload 1: TMtxVec ArcSinh

Inverse hyperbolic sine.

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

Remarks:

Calculate the inverse hyperbolic sine for all caling object elements in-place.

Examples

Matrix a = new Matrix();
a.SetIt(2, 2, false, new double[] { 0.0, 0.5, 1.0, 2.0 });
a.ArcSinh();
Matrix expected = new Matrix();
expected.SetIt(2, 2, false, new double[] { 0.0, 0.481211825059603, 0.881373587019543, 1.44363547517881 });
if (!a.IsEqual(expected, 1e-10, TCompare.cmpAbsolute))
    throw new Exception("Matrix.ArcSinh: mismatch");

Indexed: TMtxVec ArcSinh(Int32 Index, Int32 Len)

Calculate the inverse hyperbolic sine 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.

Overload 2: TMtxVec ArcSinh(TMtxVec X)

Calculate the inverse hyperbolic sine for all X object elements.

#	Name	Type	Description
1	X	TMtxVec	source TVec or TMtx

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

Remarks:

Store the results in the 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.ArcSinh(x);
Matrix expected = new Matrix();
expected.SetIt(2, 2, false, new double[] { 0.0, 0.481211825059603, 0.881373587019543, 1.44363547517881 });
if (!a.IsEqual(expected, 1e-10, TCompare.cmpAbsolute))
    throw new Exception("Matrix.ArcSinh: mismatch");

Indexed: TMtxVec ArcSinh(TMtxVec X, Int32 XIndex, Int32 Index, Int32 Len)

Calculate the inverse hyperbolic sine for X object elements [XIndex]..[XIndex+Len-1].

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

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

Remarks:

The results are stored in 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 array borders are overrun.
