The phrase "a matrix of dots" is correct and usable in written English.
It can be used to describe a pattern or arrangement that consists of multiple dots organized in a grid-like structure.
Example: "The artist created a stunning visual effect by arranging a matrix of dots in various colors across the canvas."
Alternatives: "a grid of dots" or "a pattern of dots".
In a very special case where the ion beam impinges perpendicular to the target surface, coefficients in Eq. (1) become isotropic and a regular matrix of dots is expected to be formed [16].
Since a Gram matrix is a matrix of all possible dot products, a set of also preserves the dot products of original training images.
The majority of inkjet printers operate by ejecting extremely tiny droplets of ink to form characters in a matrix of dots much like dot matrix printers.
Central pivot sprayers, drilling down to rain that fell in the last ice age, irrigated fields of potatoes — from above, they were a matrix of green, fuzzy polka dots.
Braille modified the code so that it could be read more efficiently — each letter or punctuation symbol is represented by a pattern of one to six dots on a matrix of three rows and two columns — and added abbreviations for commonly used words like "knowledge," "people" and "Lord".
The system under study is an AQDP, which is composed of two InAs quantum dots embedded in a matrix of GaAs.
which is a vector space over K spanned by matrices (S_{v_{1}+1},ldots,S_{n}). For example, if we find a matrix of rank v2=v1+o1 in, there is a high probability that the image of this matrix coincides with (phantom {dot {i}!}K^{v_{1}}oplus K^{o_{1}}) appearing in (13).
A color-coded version of a matrix dot plot is shown, generated by comparing 2 instances of the teleost repeat consensus (26 aa) against concatenated tetrapod consensus sequences from exons 15 - 23.
The algorithm is represented in a dual form such that all computation takes place using only the matrix of pairwise dot products XX′ (Shawe-Taylor and Cristianini 2004), the Gram or Kernel matrix K (Eq. 3), instead of using the data points or its variances directly.
