ippStsNanArg

This warning means at least one input argument or element is NaN. The IPP operation can continue in some routines, but the result may carry NaN forward or follow documented replacement rules.

NaN input often originates earlier: invalid normalization, division by zero, square root of a negative value or uninitialized floating-point buffers.

Check these details

Input vectors, images or coefficient arrays before the IPP call.
Earlier stages that may have produced NaN rather than reporting an error.
Whether the function documents NaN propagation or replacement behavior.
