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