Overload List
| # | Signature | Description |
|---|---|---|
| 1 | procedure SinCos(const SinX: TMtxVec; const CosX: TMtxVec); | Sine and cosine. |
| 2 | procedure SinCos(const SinX: TMtxVec; const CosX: TMtxVec; SinXIndex: Integer; CosXIndex: Integer; Index: Integer; Len: Integer); | Calculates the sine and cosine for calling object elements [Index]..[Index+Len-1]. |
Overload 1: procedure SinCos(const SinX: TMtxVec; const CosX: TMtxVec);
Sine and cosine.
Result: stored in self (calling object)
Remarks:
Calculates the sine and cosine for all calling object elements and stores the sines to SinX and cosines to CosX. Size and TMtxVec.Complex property of SinX and CosX are adjusted automatically.
Note
Use this method if you require both sine and cosine.
Examples
var a,s,c: Matrix;
begin
a.SetIt(1,3,false[0,PIDIV2,PI]);
a.Sincos(s,c); // s=[0,1,0], c =[1,0,-1]
end;Overload 2: procedure SinCos(const SinX: TMtxVec; const CosX: TMtxVec; SinXIndex: Integer; CosXIndex: Integer; Index: Integer; Len: Integer);
Calculates the sine and cosine for calling object elements [Index]..[Index+Len-1].
| # | Name | Type | Description |
|---|---|---|---|
| 1 | SinX | TMtxVec | source TVec or TMtx |
| 2 | CosX | TMtxVec | source TVec or TMtx |
| 3 | SinXIndex | Integer | |
| 4 | CosXIndex | Integer | |
| 5 | Index | Integer | start index |
| 6 | Len | Integer | element count |
Result: stored in self (calling object)
Remarks:
stores the sines to SinX elements [SinXIndex]..[SinXIndex+Len-1] and cosines to CosX elements [CosXIndex]..[CosXIndex+Len-1] elements. Size and TMtxVec.Complex property of SinX and CosX objects are not set automatically. An exception is raised if TMtxVecBase.ConditionCheck and array borders are overrun/underun.
