[Octave-bug-tracker] [bug #44315] sparse-times-single operators unimplemented

[Ceral Paquet]

Follow-up Comment #3, bug #44315 (project octave):

I emailed Tim Davis asking if there was any chance of extending SuiteSparse to
singles and he told me I need to compile it myself to get that behavior.

In fact I don't really use any of the sparse decompositions, only the basic
operations + * etc.

I'm kind of lost in the Octave sparse code - there are templates for each
supported type in:

~/octave-4.0.0/liboctave/array/Sparse*
~/octave-4.0.0/liboctave/array/MSparse*

Would it be possible to extend the core functionality of Octave to sparse
single precision? Not the SuiteSparse decompositions, just multiply and
addition.

I know Matlab does not support this but Octave is a "fixed" version of Matlab
in many ways (e.g. sparse() accepts non-double arguments).
