Sparse arrays give better performance for this task, than dense arrays, and support relatively arbitrary dimensions, but can be a bit quirky because current implementations of J do not support some features for sparse arrays. We add vectors x and y using <code>x + y</code>. Also, the first element of one of these vectors represents the "real valued" or "scalar component" of the vector.
Implementation:
