log2()

STensor syten::STensorImpl::log2

(

STensor

in

)

Takes the 2 logarithm of a rank 0 STensor.

Given a real rank-0 STensor, returns its base-2 logarithm.

Remarks

Check in with Claudius whether this is auto differentiable

This function is autodifferentiable.

This function asserts that its argument is real, as the complex case is not handled by the autodifferentiation.
