Parameters

pSrc	Pointer to the source vector.
pDst	Pointer to the destination vector.
len	Number of elements in the source and destination vectors.
pIndex	Pointer to the index of first position for the forward BWT transform.
pBWTFwdBuff	Pointer to the additional buffer.

Description

This function performs the forward BWT transform of len elements starting from pIndex element of the source vector pSrc and stores result in the vector pDst. The function uses the external buffer pBWTFwdBuff. The size of this buffer must be computed by calling the function ippsBWTFwdGetSize beforehand.

Code example shows how to use the function ippsBWTFwd_8u.

Return Values

ippStsNoErr	Indicates no error.
ippStsNullPtrErr	Indicates an error if one of the specified pointers is NULL.
ippStsSizeErr	Indicates an error if len is less than or equal to 0.
