TVec.Rotate Method

Overload List

#	Signature	Description
1	TVec Rotate(Int32 Offset)	A cyclic shift on vector elements.
	└ indexed: TMtxVec Rotate(Int32 Offset, Int32 Index, Int32 Len)
2	TMtxVec Rotate(TMtxVec Vec, Int32 Offset, Int32 VecIndex, Int32 Index, Int32 Len)	A cyclic shift on vector elements in range.

Overload 1: TVec Rotate(Int32 Offset)

A cyclic shift on vector elements.

#	Name	Type	Description
1	Offset	Int32

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

Remarks:

Performs cyclic shift on vector elements. The number of elements to shift is specified in the Offset parameter. Offset can be any integer number, positive or negative.

Examples

TVec a;
MtxVec.CreateIt(out a);
try
    {
        a.SetIt(false,new double[] {1,2,3,4});
        a.Rotate(2);   // a = new double[] {3,4,1,2}
    }
finally
    {
        MtxVec.FreeIt(ref a);
    }

Indexed: TMtxVec Rotate(Int32 Offset, Int32 Index, Int32 Len)

A cyclic shift on vector elements in range.

#	Name	Type	Description
1	Offset	Int32
2	Index	Int32	start index
3	Len	Int32	element count

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

Remarks:

Performs cyclic shift on vector elements in specified range [Index..Index+Len]. The number of elements to shift is specified in the Offset parameter. Offset can be any integer number, positive or negative.

Overload 2: TMtxVec Rotate(TMtxVec Vec, Int32 Offset, Int32 VecIndex, Int32 Index, Int32 Len)

A cyclic shift on vector elements in range.

#	Name	Type	Description
1	Vec	TMtxVec	source TVec or TMtx
2	Offset	Int32
3	VecIndex	Int32
4	Index	Int32	start index
5	Len	Int32	element count

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

Remarks:

Performs cyclic shift on source vector elements in specified range [Index..Index+Len] and stores them to calling vector. The number of elements to shift is specified in the Offset parameter. Offset can be any integer number, positive or negative.
