SubbandProcessGetSize

Calculates size of the subband process state structure.

Syntax

IppStatus ippsSubbandProcessGetSize_32f(int order, int windowLen, int* pStateSize, int* pInitBufSize, int* pBufSize);

IppStatus ippsSubbandProcessGetSize_16s(int order, int windowLen, int* pStateSize, int* pInitBufSize, int* pBufSize);

Parameters

order	Number of subbands is equal to 2^{order - 1} + 1.
windowLen	Length of window.
pStateSize	Pointer to the computed value of buffer size for the subband process state structure.
pInitBufSize	Pointer to the computed buffer size for use in the initialization function.
pBufSize	Pointer to the computed size of work buffer.

Description

The functions ippsSubbandProcessGetSize are declared in the ippsc.h file. These functions calculate the sizes of memory buffers required for the functions ippsSubbandAnalysis and ippsSubbandSynthesis to operate.

Return Values

ippStsNoErr	Indicates no error.
ippStsNullPtrErr	Indicates an error when one of the specified pointers is NULL.
ippStsBadArgErr	Indicates an error when order is less than or equal to 0 or when windowLen is not divisible by 2^order.
