Parameters
- pState
- Pointer to the sparse FIR filter state structure.
- pDlyLine
- Pointer to the array holding the delay line values.
Description
This function copies the delay line values from the state
structure
pState
and
stores them into pDlyLine
. The destination array pDlyLine
contains samples in
the reverse order as compared to the order of samples in the source vector.Before calling
ippsFIRSparseGetDlyLine
, 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.
