## Input Parameters
- ***X -*** nest vector
- ***N -*** number of component vecs in `sx`
- ***idxm -*** indices of component vectors that are to be replaced
- ***sx -*** array of vectors
## Note
The components in the vector array `sx` do not have to be of the same size as corresponding
components in `X`. The user can also free the array `sx` after the call.
