Is cholupdate not supported for sparse matrices?

I have a large sparse matrix `A` and I issue:

    [L,p] = chol(A);

Then I try to delete a row using

    [L1] = cholupdate(A,L(:,1),'-');

I get the error:

    Undefined function 'cholupdate' for input arguments of type 'double' and attributes
'sparse 2d real'.

However this works if I make `A` full (dense).

So is cholupdate not supported for sparse matrices?
