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. |
