include test cases + Added the NDArray_Cum_Sum function to perform cumulative sum operations on NDArray objects. + Exposed the NDArray_Cum_Sum function to PHP via the cumSum method in numpower class. + Implemented the cumSum method to handle optional axis parameters, where the default operation will be on a flattened matrix. + Ensured that the new functionality integrates seamlessly with existing NDArray operations and maintains overall code integrity. + Added test cases for cumSum function to confirm correctness. + Verified that all tests pass successfully, confirming the correctness of the new cumulative sum functionality. --- numpower.c | 29 ++++++++++++ src/ndmath/arithmetics.c | 31 ++++++++++-- src/ndmath/arithmetics.h | 1 + tests/math/045-ndarray-cumsum.phpt | 76 ++++++++++++++++++++++++++++++ 4 files changed, 132 insertions(+), 5 deletions(-) create mode 100644 tests/math/045-ndarray-cumsum.phpt diff --git a/numpower.c b/numpower.c index 554972d..bede2d7 100644 --- a/numpower.c +++ b/numpower.c @@ -4777,6 +4777,33 @@ PHP_METHOD(NDArray, cumProd) { RETURN_NDARRAY(rtn, return_value);
