TMtx.Cosh Method — Dew Math

Overload List

#	Signature	Description
1	TMtxVec Cosh	Hyperbolic cosine.
	└ indexed: TMtxVec Cosh(Int32 Index, Int32 Len)
2	TMtxVec Cosh(TMtxVec X)	Calculate the hyperbolic cosine for all X object elements.
	└ indexed: TMtxVec Cosh(TMtxVec X, Int32 XIndex, Int32 Index, Int32 Len)

Overload 1: TMtxVec Cosh

Hyperbolic cosine.

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

Remarks:

Calculate the hyperbolic cosine of 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.Cosh();
Matrix expected = new Matrix();
expected.SetIt(2, 2, false, new double[] { 1.0, 1.12762596520638, 1.54308063481524, 3.76219569108363 });
if (!a.IsEqual(expected, 1e-10, TCompare.cmpAbsolute))
    throw new Exception("Matrix.Cosh: mismatch");

Matrix a;
Matrix b;
a.SetIt(2,2,false,new double[] {1,1.5,2,0.3});
a.Cosh;  //or
a = Cosh(a); //internally becomes a.Cosh (in-place operation)
b.Cosh(a);
b = Cosh(a);

Indexed: TMtxVec Cosh(Int32 Index, Int32 Len)

Calculate the hyperbolic cosine 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 Cosh(TMtxVec X)

Calculate the hyperbolic cosine 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.Cosh(x);
Matrix expected = new Matrix();
expected.SetIt(2, 2, false, new double[] { 1.0, 1.12762596520638, 1.54308063481524, 3.76219569108363 });
if (!a.IsEqual(expected, 1e-10, TCompare.cmpAbsolute))
    throw new Exception("Matrix.Cosh: mismatch");

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

Calculate the hyperbolic cosine 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.
