ippStsSparseErr
Sparse filtering uses explicit tap positions instead of a dense coefficient vector. IPP reports this status when those positions are not a valid sparse impulse-response description.
Look for duplicate, negative or unsorted positions before investigating the samples. The coefficient values can be numerically valid while the sparse layout is still unusable.
Check these details
- Tap positions are strictly ascending.
- No position is negative or repeated.
- The number of positions matches the number of supplied tap coefficients.
