How to delete zeros from matrix delete and delete! does not work?

[kristoffer.carlsson]

Let’s say you have:

[1 0 1;
 0 1 1;
 0 0 1]

What do you want the result of “delete zeros” to be?

[spaceLem]

Just in case you’re talking about sparse matrices, then the functions you’re looking for are dropzeros() and dropzeros!().

in what packgate is because it doesn;t work?

If dropzeros doesn’t work then it won’t be applicable to your case — it only applies to SparseArrays.

Probably what you want is something like filter(!iszero, A), which will return all nonzero elements as a vector… but you could also reasonably want all rows without any nonzeros, or all rows that aren’t all nonzero, or …, or …

We need a bit more to go on
