I'm very sorry, but we have no current plans to enhance this function.
'ippSVDSort' is part of the speech recognition domain. The speech recognition domain has been removed from the 7.0 product and will only continue to be supported in the 6.1 product.
I'm not aware of any sample for this function, and I'm not expert at this function. According to the documentation:
This function performs Single Value Decomposition (SVD) on the input matrix A. The output matrices U, W, and V meet the following condition:
A = U W VT,
where the matrix U is column-orthogonal, the matrix W is diagonal (stored as a vector), and the matrix V is orthogonal. VT is the transpose of the matrix V.
The function ippsSVDSort transforms output matrices so that elements of the matrix W are sorted in descending order of their absolute values.
