Overload List
| # | Signature | Description |
|---|---|---|
| 1 | TMtxVec *Abs(); | Absolute values. |
| 2 | TMtxVec *Abs(int Index, int Len); | Calculate the absolute value for calling object elements [Index]..[Index+Len-1]. |
| 3 | TMtxVec *Abs(TMtxVec *X); | Calculate the absolute value for all X object and store the results in the calling object. |
