Overload List
| # | Signature | Description |
|---|---|---|
| 1 | TVecInt Difference(TMtxVecInt Vec, Int32 Lag) | Calculate the difference for all Vec elements. |
| 2 | TVecInt Difference(Int32 Lag) | The difference between two succesive vector elements. |
| 3 | TMtxVecInt Difference(TMtxVecInt Vec, Int32 VecIndex, Int32 Index, Int32 Len) | Difference. |
Overload 1: TVecInt Difference(TMtxVecInt Vec, Int32 Lag)
Calculate the difference for all Vec elements.
| # | Name | Type | Description |
|---|---|---|---|
| 1 | Vec | TMtxVecInt | source TVecInt or TMtxInt |
| 2 | Lag | Int32 |
Result: stored in self (calling object), returns self for chaining
Store the results in the calling vector. The Dew.Math.TMtxVecBase.Length of the calling vector is set to one less the length of Vec.
Overload 2: TVecInt Difference(Int32 Lag)
The difference between two succesive vector elements.
| # | Name | Type | Description |
|---|---|---|---|
| 1 | Lag | Int32 |
Result: stored in self (calling object), returns self for chaining
Calculate the difference for all calling vector elements. The following formula is used to calculate the difference:
The Length of calling vector is automatically decremented by one.
Overload 3: TMtxVecInt Difference(TMtxVecInt Vec, Int32 VecIndex, Int32 Index, Int32 Len)
Difference.
| # | Name | Type | Description |
|---|---|---|---|
| 1 | Vec | TMtxVecInt | source TVecInt or TMtxInt |
| 2 | VecIndex | Int32 | |
| 3 | Index | Int32 | start index |
| 4 | Len | Int32 | element count |
Result: stored in self (calling object), returns self for chaining
Calculate the difference for Vec elements [VecIndex]..[VecIndex+Len-1] and store the results in the calling object elements [Index]..[Index+Len-1]. Size of the calling vector must be set explicitly. The following formula is used to calculate the difference:
An exception is raised if Dew.Math.VectorInt.ConditionCheck is True and array borders are overrun or underrun.
