FIRSparseSetDlyLine

Sets the delay line contents in the sparse FIR filter state structure.

Syntax

IppStatus ippsFIRSparseSetDlyLine_32f(IppsFIRSparseState_32f* pState, const Ipp32f* pDlyLine);

IppStatus ippsFIRSparseSetDlyLine_32fc(IppsFIRSparseState_32fc* pState, const Ipp32fc* pDlyLine);

Libraries: ippcore.lib, ippvm.lib

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 the pState pointer is NULL.
ippStsContextMatchErr	Indicates an error when the state identifier is incorrect.
