Singular

When used as a simple adjective in English, singular usually means unique.

The singular is one of two grammatical numbers in English; the other is the plural.

In mathematics singular has a number of meanings

• A square matrix is called singular if it is not invertible.
• In complex analysis, a singular point of a function f is a point such that f is analytic in its neighbourhood but not at it. See mathematical singularity.
• A measure or distribution is called singular if its support has zero Lebesgue measure. More generally, one may talk about an object "singular with respect to a measure μ", and that means that μ replaces the Lebesgue measure above.

SINGULAR is also the name of a computer algebra system.

See also gravitational singularity.

Singular (أَحَدٌ) is one of God's Names as described in Sura 112 in the Quran:

"Say: He is Allah, Singular. Allah, the Absolute. He begetteth not nor was begotten. And to Him have never been one equal."
