Workspace Method retrievalAddPolyfit


Same as jacobianAddPolyfit but also adds a new block to covmat_sx
using the matrices in covmat_block and covmat_inv_block.

If covmat_inv_block is non-empty, it is used as inverse for the added block
which avoids its numerical computation.

For number and order of elements added to x, see jacobianAddPolyfit.
