One way to visualize the similarity between two protein or nucleic acid sequences is to use a similarity matrix, known as a dot plot. These were introduced by Gibbs and McIntyre in 1970 [1] and are two-dimensional matrices that have the sequences of the proteins being compared along the vertical and horizontal axes.

A dot matrix is a 2-dimensional patterned array, used to represent characters, symbols and images. Most types of modern technology use dot matrices for display of information ...
The dot-matrix approach, which implicitly produces a family of alignments for individual sequence regions, is qualitative and conceptually simple, though time-consuming to analyze on a large scale. In the absence of noise, it can be easy to visually identify certain sequence features—such as insertions, deletions, repeats, or inverted repeats ...
Dot matrix printing is typically distinguished from non-impact methods, such as inkjet, thermal, or laser printing, which also use a bitmap to represent the printed work. These other technologies can support higher dot resolutions and print more quickly, with less noise.
The alignment of individual motifs is then achieved with a matrix representation similar to a dot-matrix plot in a pairwise alignment. An alternative method that uses fast local alignments as anchor points or seeds for a slower global-alignment procedure is implemented in the CHAOS/DIALIGN suite. [20]
The reason given is: Printing and display technology progresses. There's been less need for hard copies, and better non-thermal printers as well, shifting the demand and application of thermal printers. The comparison with the largely obsolete (for about 20 years!) technology of dot-matrix impact printing is very emblematic for this issue.
Soaking your hair in rice water is another method, which "seems to be the way to get the best benefit," she adds. While Khetarpal doesn't inherently recommend using rice water to promote hair ...
A dot matrix is a 2-dimensional array of dots used to represent characters, symbols and images. "Dot matrix" may also refer to:- Dot matrix printing (or impact matrix printing), a type of computer printing; Dot matrix printers, computer printers that implement dot-matrix impact printing; Dot-matrix display, a type of display device
