Overload 1: TMtxVec ThreshBottom(TMtxVec Src, Double Value)
Perform threshold operation on all Src object values.
| # | Name | Type | Description |
|---|---|---|---|
| 1 | Src | TMtxVec | source TVec or TMtx |
| 2 | Value | Double | scalar |
Result: stored in self (calling object), returns self for chaining
Store the results in calling object. Size and Dew.Math.TMtxVec.Complex properties of the calling object are adjusted automatically.
Indexed: TMtxVec ThreshBottom(TMtxVec Vec, Double Value, Int32 VecIndex, Int32 Index, Int32 Len)
Perform a threshold operation on Vec elements [VecIndex]..[VecIndex+Len-1].
| # | Name | Type | Description |
|---|---|---|---|
| 1 | Vec | TMtxVec | source TVec or TMtx |
| 2 | Value | Double | scalar |
| 3 | VecIndex | Int32 | |
| 4 | Index | Int32 | start index |
| 5 | 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.TMtxVec.Complex properties of the calling object must be set explicitly. An exception is raised if Dew.Math.TMtxVecBase.ConditionCheck is true and array borders are overrun/underrun.
Overload 2: TMtxVec ThreshBottom(Double Value)
Threshold bottom operation.
| # | Name | Type | Description |
|---|---|---|---|
| 1 | Value | Double | scalar |
Result: stored in self (calling object), returns self for chaining
Perform threshold operation on all calling object values. The Value parameter is a lower bound for threshold operation. All values smaller than Value will be replaced with Value.
