What does Intel IPP status -29 (ippStsFIRMRFactorErr) mean?

ippStsFIRMRFactorErr

FIRMR routines use a multirate FIR structure where the factor controls interpolation or decimation steps. A non-positive factor cannot select a valid phase sequence.

Validate the resampling ratio and the FIRMR initialization parameters together; the processing call inherits that contract.

Check these details for ippStsFIRMRFactorErr

• The factor used at FIRMR initialization.
• Coefficient layout for the expected number of phases.
• Whether the ratio changed without rebuilding the state object.
