Re: [Pysparse-users] Comlpex numbers

[Roman G. <rom...@gm...>]

Hello

pysparse only deals with double precision real numbers. The was a 
followup project called pysparse2, implemented with C++ templates that 
was intended to support arbitrary matrix element types. Unfortunately 
pysparse2 was never completed. So it's just doubles now.

Regards,
Roman
