The previous definition agrees with the one for matrices given in the introduction to this article, if we take as H the Hilbert space C < sup > n </ sup > with the standard dot product and interpret a square matrix as a linear operator on this Hilbert space.

This should be clearly distinguished from Unicode characters that are rendered as identical glyphs or near-identical glyphs ( homoglyphs ), either because they are historically cognate ( such as Greek Η vs. Latin H ) or because of coincidental similarity ( such as Greek Ρ vs. Latin P, or Greek Η vs. Cyrillic Н, or the astronomical symbol for " Sun " ☉ vs. " circled dot operator " ⊙ vs. the Gothic letter vs. the IPA symbol for a bilabial click ʘ ).

also place three dots on the specimen at each side of the 10 inch square, one dot at midpoint, and one at approximately 1/2 inch from each corner.

Because far less motion was involved than in a conventional dot matrix printer, these printers were very fast compared to dot matrix printers and were competitive in speed with formed-character line printers while also being able to print dot matrix graphics.

The tilde, dot, comma, titlo, apostrophe, bar, and colon are sometimes diacritical marks, but also have other uses.

:* Maltese uses a C, G, and Z with a dot over them ( Ċ, Ġ, Ż ), and also has an H with an extra horizontal bar.

From the 6th century BC, they are separated by a dot or a colon, which symbol might also be used to separate syllables.

The natural way to obtain these quantities is by introducing and using the standard inner product ( also known as the dot product ) on R < sup > n </ sup >.

Today, the most widely recognized standards for this mechanical structure are IEEE 1101. 1, IEEE 1101. 10 ( also known commonly as " dot ten ") and IEEE 1101. 11.

The Bakhshali manuscript also " employs a decimal place value system with a dot for zero.

Inner product spaces generalize Euclidean spaces ( in which the inner product is the dot product, also known as the scalar product ) to vector spaces of any ( possibly infinite ) dimension, and are studied in functional analysis.

LCD spatial performance is also sometimes described in terms of a " dot pitch ".

where · denotes the dot product, see also orthogonality for more information.

By using a dot to divide the digits into two groups, one can also write fractions in the positional system.

There was also a set neck 4000 version in 1975 and 76 ( neck set like a Gibson Les Paul ) which had a 20-fret neck, dot inlays, no binding ( similar to the 4001S ) but only a single bridge position mono pickup.

When the length of vectors is defined, it is possible to also define a dot product — a scalar-valued product of two vectors — which gives a convenient algebraic characterization of both length ( the square root of the dot product of a vector by itself ) and angle ( a function of the dot product between any two vectors ).

However, some languages also allow other sounds to form the nucleus of a syllable, such as the syllabic l in the English word table ( the stroke under the l indicates that it is syllabic ; the dot separates syllables ), or the r in Serbo-Croatian vrt " garden ".

* Full stop, also called a period – a dot at the end of a sentence

Some bands use small notebooks, also known as a dot book or drillbook, which they hang about their necks, on the drum harness, or around the waist.

He also experimented with pointillism, enlarged half-tone dot grids ( which Roy Lichtenstein would later use ), and stereoscopic images.

Because far less printhead motion was involved than in a conventional dot matrix printer, these printers were much faster than dot matrix printers and were competitive in speed with formed-character line printers while also being able to print dot-matrix graphics as well as variable-sized characters.

Each dot is produced by a tiny metal rod, also called a " wire " or " pin ", which is driven forward by the power of a tiny electromagnet or solenoid, either directly or through small levers ( pawls ).

It is so called because the inner product ( or dot product ) of two states is denoted by a bra | c | ket ;

There is a notable feast in Teochew cuisine / banquet called jiat dot ().

As compared to dot matrix printers that print a single column of dots at a time, these printers generally print an entire line of dots at a time and so are sometimes called line matrix printers.

Names and proper nouns are preceded with a mid-line dot ( called a name-dot ) which is sufficient to distinguish them from ordinary words.

In the nations of the British Empire, although the full stop could be used in typewritten material, the point ( mid dot: ·), which can also be called an interpunct ( often referred to as the decimal point ) was preferred for the decimal mark in printing technologies that could accommodate it.

This zone might also be called the dot zone, because its pattern of Y: 讠 U: 冫 I: 氵 and O: 灬 is not actually necessarily built up of right falling strokes.

The farmers prospered, establishing a Grange Hall and, in 1872, a small schoolhouse called the " Live Oak School ", named for the evergreen live oak trees that dot the area.

An interpunct ( · ), also called an interpoint, is a punctuation mark consisting of a dot used for interword separation in ancient Latin script and in some modern languages as a stand-alone sign inside a word.

The dot is vertically centered, e. g. " DONA · EIS · REQVIEM ", and is therefore also called a middle dot or centered dot ( Commonwealth: centred dot ).
