How many items are not sparse
Iterator of indices and values of all non-sparse values
Grow by adding count sparse values to the end
(Changed in version 2.9.0) The behavior of scanRight has changed. The previous behavior can be reproduced with scanRight.reverse.
(Changed in version 2.9.0) transpose throws an IllegalArgumentException if collections are not uniformly sized.
An IndexedSeq that automatically switches representation between dense and sparse depending on sparsity Should be an efficient representation for all sizes, and it should not be necessary to special case immutable algebras based on the sparsity of the vectors.
