Redirect to:

This page is a redirect. The following categories are used to track and monitor this redirect:

From a subtopic: This is a redirect from a subtopic of the target article or section.
- If the redirected subtopic could potentially have its own article in the future, then also tag the redirect with {{R with possibilities}} and {{R printworthy}}.

From an avoided double redirect: This is a redirect from an alternative title or related topic of Positive-definite matrix, another redirect to the same title. Because double redirects are disallowed, both pages currently point to Definite matrix.
- If Positive-definite matrix is retargeted or is expanded into a separate article, template, or other project page, this redirect will be recategorized to be updated.

From the plural form: This is a redirect from a plural noun to its singular form.
- This redirect link is used for convenience; it is often preferable to add the plural directly after the link (for example, [[link]]s). However, do not replace these redirected links with a simpler link unless the page is updated for another reason (see WP:NOTBROKEN).
- Use this rcat to tag only mainspace redirects; when plural forms are found in other namespaces, use {{R from modification}} instead.

When appropriate, protection levels are automatically sensed, described and categorized.
