Matrix Class

Overload List

#SignatureDescription
1function Cot: TMtxVec;Cotangens.
└ indexed: function Cot(Index: Integer; Len: Integer): TMtxVec;
2function Cot(const X: TMtxVec): TMtxVec;Calculate the cotangens of all X object elements and store the results in the calling object.
└ indexed: function Cot(const X: TMtxVec; XIndex: Integer; Index: Integer; Len: Integer): TMtxVec;

Overload 1: function Cot: TMtxVec;

Cotangens.

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

Remarks:

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

Examples
var a: Matrix;
begin
    a.SetIt(1,2,True,[1,-2,3,4]);
    a.Cot; // Computes complex cotangens
end;
See Also: Matrix.Tan, Matrix.ArcCot

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

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

#NameTypeDescription
1IndexIntegerstart index
2LenIntegerelement count

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

Remarks:

An exception is raised if array borders are overrun.

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

Calculate the cotangens of all X object elements and store the results in the calling object.

#NameTypeDescription
1XTMtxVec

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

Remarks:

Size and Matrix.Complex properties of calling object are adjusted automatically.

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

Calculate the cotangens of X object elements [XIndex]...[XIndex+Len-1]. The results are stored in calling object elements [Index]...[Index+Len-1].

4LenIntegerelement count

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

Remarks:

Size and Matrix.Complex properties of the calling object must be set explicitly. An exception is raised if array borders are overrun.
