[35s] Valentin Albillo's complex solver sources?

[emece67]

Hi all, when dealing with the complex solver in the wp34s, I've found that it is a porting from a complex solver by Valentín Albillo for the 35s.

Although Valentín posted years ago links to such article, now those links are broken. Does anybody have a copy of the Valentín's article describing such solver. The porting for the wp34s does not have any information about the inner workings.

Thanks & regards.
