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 whenpBufferSizepointer isNULL.
- ippStsIIROrderErr
- Indicates an error whenorderis less than or equal to 0.
