Domain Dependencies

Headers: ippcore.h, ippvm.h

Libraries: ippcore.lib, ippvm.lib

Parameters

order

Order of the IIR filter.

pBufferSize

Pointer to the computed buffer size value.

Description

This function computes the size of the external buffer for an arbitrary IIR filter state, and stores the result in pBufferSize.

To compute a size of the buffer, the filter order parameter order must be specified.

Return Values

ippStsNoErr

Indicates no error.

ippStsNullPtrErr

Indicates an error when pBufferSize pointer is NULL.

ippStsIIROrderErr

Indicates an error when order is less than or equal to 0.
