Parameters
- pState
- Pointer to the FIR filter state structure.
- pDlyLine
- Pointer to the array holding the delay line values.
Description
This function copies the delay line values from
pDlyLine
and stores them into the state structure pState
. The source array pDlyLine
must contain samples in the reverse order as compared to the order of samples in the source vector.Before calling
ippsFIRSparseSetDlyLine
, the corresponding filter state structure must be initialized with the FIRSparseInit
function.Return Values
- ippStsNoErr
- Indicates no error.
- ippStsNullPtrErr
- Indicates an error when thepStatepointer isNULL.
- ippStsContextMatchErr
- Indicates an error when the state identifier is incorrect.
