Vector.Csc Method

Overload List

#	Signature	Description
1	function Csc: TMtxVec;	Cosecant.
	└ indexed: function Csc(Index: Integer; Len: Integer): TMtxVec;
2	function Csc(const X: TMtxVec): TMtxVec;	Calculate the cosecant of all X object elements.
	└ indexed: function Csc(const X: TMtxVec; XIndex: Integer; Index: Integer; Len: Integer): TMtxVec;

Overload 1: function Csc: TMtxVec;

Cosecant.

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

Remarks:

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

Examples

var a: Vector;
begin
    a.SetIt(True,[1,-2,3,4]);  // a = [1-2i, 3+4i]
    a.Csc; // Computes complex cosecant
end;

Indexed: function Csc(Index: Integer; Len: Integer): TMtxVec;

Calculate the cosecant of calling object elements [Index]...[Index+Len-1] in-place.

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

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

Remarks:

An exception is raised if array borders are overrun.

Overload 2: function Csc(const X: TMtxVec): TMtxVec;

Calculate the cosecant of all X object elements.

#	Name	Type	Description
1	X	TMtxVec

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

Remarks:

Store the results in the calling object. Size and Vector.Complex properties of calling object are adjusted automatically.

Indexed: function Csc(const X: TMtxVec; XIndex: Integer; Index: Integer; Len: Integer): TMtxVec;

Calculate the cosecant of X object elements [XIndex]...[XIndex+Len-1].

#	Name	Type	Description
1	X	TMtxVec
2	XIndex	Integer	X start index
3	Index	Integer	start index
4	Len	Integer	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 Vector.Complex properties of the calling object must be set explicitly. An exception is raised if array borders are overrun.
