function Difference(const Vec: TMtxVecInt; VecIndex: Integer; Index: Integer; Len: Integer; Lag: Integer): TMtxVecInt;
Difference.
| # | Name | Type | Description |
|---|---|---|---|
| 1 | Vec | TMtxVecInt | source TVecInt or TMtxInt |
| 2 | VecIndex | Integer | |
| 3 | Index | Integer | start index |
| 4 | Len | Integer | element count |
| 5 | Lag | Integer |
Result: stored in self (calling object), returns self for chaining
Remarks:
Calculate the difference for Vec elements [VecIndex]..[VecIndex+Len-1] and store the results in the calling object elements [Index]..[Index+Len-1]. Size and of the calling vector must be set explicitly. The following formula is used to calculate the difference:
An exception is raised if TMtxVecBase.ConditionCheck is True and array borders are overrun or underrun.
