Overload 1: TOpenCLMtxVec Log2
Log base 2.
Result: stored in self (calling object), returns self for chaining
Calculate the log base 2 for all calling object elements in-place.
clMatrix a;
a.CopyFromArray(2,2,TSingleArray.Create(1,2,4,8));
a.Log2;Indexed: TOpenCLMtxVec Log2(Int32 Index, Int32 Len)
Calculate the log base 2 for 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
An exception is raised if array borders are overrun.
Overload 2: TOpenCLMtxVec Log2(TOpenCLMtxVec X)
Calculate the log base 2 for all X elements.
| # | Name | Type | Description |
|---|---|---|---|
| 1 | X | TOpenCLMtxVec | source TOpenCLVector or TOpenCLMatrix |
Result: stored in self (calling object), returns self for chaining
Store the results in the calling object. Size and Dew.Math.TOpenCLBase.Complex properties of the calling vector are set implicitly to match the X object.
Indexed: TOpenCLMtxVec Log2(TOpenCLMtxVec X, Int32 XIndex, Int32 Index, Int32 Len)
Calculate the log base 2 for X elements [XIndex]..[XIndex+Len-1].
| # | Name | Type | Description |
|---|---|---|---|
| 1 | X | TOpenCLMtxVec | source TOpenCLVector or TOpenCLMatrix |
| 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
Store the results in the calling object elements [Index]..[Index+Len-1]. Size and Dew.Math.TOpenCLBase.Complex properties of the calling object must be set explicitly. An exception is raised if array borders are overrun.
