make the Python wrapper accept pre-allocated output array #164

Closed paskino closed 8 months ago

paskino commented 3 years ago

It'd be nice if the Python wrapper would allow the user to pass a pre allocated array for output instead of allocating the output by default.

dkazanc commented 3 years ago

so it's an initialisation of a sort? Could be useful indeed.

not really an initialisation, but the Python wrapper allocates by itself the output of the regularisation, like here in TV_ROF.

The wrapper should allow to pass an already allocated array. In case none is passed it should allocate it.
