I'd like to suggest merging these two tags for the following reasons.
- Both tags are under-utilized; many questions cover the topic of matrix conditioning, either in statement or in answers, but are not tagged as such. This may occur in part due to tag ambiguity.
- There are only 4 questions tagged with conditioning compared to 16 with condition-number, but the topics covered are essentially identical.
- The notions of matrix conditioning and condition number are inextricably linked; the former refers to the magnitude of the latter.
Is there any reason we should keep these tags separate or hesitate in enacting a global merge?
