           Summary: INTEG() and DERIV() operators for equations
           Product: kst
           Version: unspecified
          Platform: unspecified
        OS/Version: Solaris
            Status: UNCONFIRMED
          Severity: wishlist
          Priority: NOR
         Component: general
        AssignedTo: kst kde org
        ReportedBy: nicolas.brisset eurocopter com

Version:           1.0.0_devel (using KDE 3.3.0, compiled sources)
Compiler:          gcc version 3.3.2
OS:                SunOS (sun4u) release 5.8

In the (long and growing) "I need more operators for equations" series, would it be possible to add INTEG() and DERIV() operators ?
- INTEG could have two different syntaxes: INTEG(Vec1), which would just compute the cumulative sum of all values, and INTEG(Vec1,Vec2) which would integrate i.e. add at each step Vec1(n)*(Vec2(n) - Vec2(n-1))
- DERIV in more or less the same fashion.
