sign.default

<code>sign</code> returns a vector with the signs of the corresponding
 elements of <code>x</code> (the sign of a real number is 1, 0, or \(-1\)
 if the number is positive, zero, or negative, respectively).
Note that <code>sign</code> does not operate on complex vectors.

The 'KeOps' library lets you compute generic reductions of
very large arrays whose entries are given by a mathematical formula
with CPU and GPU computing support. It combines a tiled reduction
scheme with an automatic differentiation engine. It is perfectly
suited to the efficient computation of Kernel dot products and the
associated gradients, even when the full kernel matrix does not fit
into the GPU memory.
