Create the following cumulative matrix functions:

  • cumsum(MAT, BASE=0) -> MAT (Cumulative sum, will add cumulative to the BASE matrix)
  • cumprd(MAT, BASE=1) -> MAT (Cumulative product, will multiply cumulative with the BASE matrix)

Analysis:

We will omit those BASE parameters as these are either realizable as pre- or post-operation operands and will therefore only result in misunderstandings. Instead we'll use the second parameter to define the direction of application for actual matrices (for vectors it is obvious). As a reference of application, we'll use the dimension logic of the unique() matrix function.

Implementation:

  • Implementation: Implemented as proposed by the analysis.
  • Revision: [r1307]
  • Implementation test: Both functions were tested on a human-readable matrix.

Documentation:

  • [x] ChangesLog updated
  • [x] Code changes commented
  • Documentation articles:
    • [x] corresponding documentation articles updated
    • [ ] new documentation articles created
    • [ ] not needed
  • Language files:
    • [x] corresponding language files updated
    • [ ] not needed

Tests:

Functions were added to the automatic SW tests. No deviations detected.
