TVec.Cot Method — Dew Math

Overload List

#	Signature	Description
1	TMtxVec Cot	Cotangens.
	└ indexed: TMtxVec Cot(Int32 Index, Int32 Len)
2	TMtxVec Cot(TMtxVec X)	Calculate the cotangens of all X object elements.
	└ indexed: TMtxVec Cot(TMtxVec X, Int32 XIndex, Int32 Index, Int32 Len)

Overload 1: TMtxVec Cot

Cotangens.

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

Remarks:

Calculate the cotangens of all caling object elements in-place.

Examples

Vector a;
a.SetIt(true,new double[] {1,-2,3,4});
a.Cot; // Computes complex cotangens

Indexed: TMtxVec Cot(Int32 Index, Int32 Len)

Calculate the cotangens of 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 Cot(TMtxVec X)

Calculate the cotangens of 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.

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

Calculate the cotangens of 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.
