ippStsIIROrderErr
Recursive IIR filters keep state and use denominator feedback terms. The order must match the coefficient and delay-line layout expected by the selected routine.
An invalid order usually means the filter description and state buffer were built for a different API variant or different section layout.
Check these details
- The order passed to initialization and processing calls.
- Coefficient array length for numerator and denominator terms.
- Delay-line/state allocation for the same order.
