Hi,

I have a NxM matrix and I would like to extract some rows / columns. I have try to use the matrix_slice command, but I need specify only the rows / columns and need the full range for columns / rows:

For illustrating (not syntactic correct):

unsigned int rows[5];

// dynamic fill rows[i]

ublas::matrix_slice< ublas::matrix<double> > extract(mymatrix, ublas::slice(rows), ublas::range(0, mymatrix::size2()-1));

// create

ublas::matrix<double> newmatrix = extract;

How can I create a new matrix with the full row / column range from some columns / rows?

Thanks

Phil
