Subject: [ublas] submatrix with indexvector

Hello,
can I extract a submatrix from a ublas::matrix with an indexvector?
I've got a ublas::vector with index values and a
ublas::matrix(1000,1000). The indexvector holds only 12 index position
and I need something like:
ublas::matrix x(1000,1000);
project(x, indexvector, indexvector) += other matrix with
indexvector.size x indexvector.size
I must cut a submatrix which is not continously and adds another
matrix. Are there any boost operations or should I run over all
elements?
Thanks
Phil
