TVec.Sin Method — Dew Math

Overload List

#	Signature	Description
1	TMtxVec Sin	Sine function.
	└ indexed: TMtxVec Sin(Int32 Index, Int32 Len)
2	TMtxVec Sin(TMtxVec X)	Calculate the sine of all X object elements and store the results in calling object.
	└ indexed: TMtxVec Sin(TMtxVec X, Int32 XIndex, Int32 Index, Int32 Len)

Overload 1: TMtxVec Sin

Sine function.

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

Remarks:

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

Examples

Vector a = new Vector();
a.SetIt(new double[] { 0.0, 0.523598775598299, 0.785398163397448, 1.0471975511966 });
a.Sin();
Vector expected = new Vector();
expected.SetIt(new double[] { 0.0, 0.5, 0.707106781186548, 0.866025403784439 });
if (!a.IsEqual(expected, 1e-10, TCompare.cmpAbsolute))
    throw new Exception("Vector.Sin: mismatch");

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

Indexed: TMtxVec Sin(Int32 Index, Int32 Len)

Calculate the sine 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 Sin(TMtxVec X)

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

#	Name	Type	Description
1	X	TMtxVec	source TVec or TMtx

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

Remarks:

Size and Dew.Math.TMtxVec.Complex properties of calling object are adjusted automatically.

Examples

Vector a = new Vector();
Vector x = new Vector();
x.SetIt(new double[] { 0.0, 0.523598775598299, 0.785398163397448, 1.0471975511966 });
a.Sin(x);
Vector expected = new Vector();
expected.SetIt(new double[] { 0.0, 0.5, 0.707106781186548, 0.866025403784439 });
if (!a.IsEqual(expected, 1e-10, TCompare.cmpAbsolute))
    throw new Exception("Vector.Sin: mismatch");

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

Calculate the sine 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.
