.PP
Constructor which implements the QUIC-SVD algorithm\&. The function calls the CosineTree constructor to create a subspace basis, where the original matrix's projection has minimum reconstruction error\&. The constructor then uses the \fBExtractSVD()\fP function to calculate the SVD of the original dataset in that subspace\&.
