array An ordered arrangement of data items. A vector is a one dimensional array; a matrix is a two-dimensional array. Arrays are used in myriad applications from basic database processing to scientific simulation. Most programming languages support arrays by providing indexes into the data.

Array An array is a kind of aggregate data type. A single ordinary variable (a scalar) could be considered as a zero-dimensional array. A one-dimensional array is also known as a vector. A reference to an array element is written something like A[i,j,k] where A is the array name and i, j and k are the indices. The C language is peculiar in that each index is written in separate brackets, e.g. A[i][j][k].

- JBuilder. Vector graphics is the creation of digital images through a sequence of commands or mathematical statements that place lines and shapes in a given two-dimensional or three-dimensional space. In physics, a vector is a representation of both a quantity and a direction at the same time.

- So, on to... Acessing Elements of a Vector. There are a number of ways to access the elements of a vector. For the moment, I will focus on two of them, one safe and one unsafe. And as a reminder, C++ vectors (and other STL containers), like raw C/C++ arrays, are accessed with indices starting at zero.ntroduction. --------------. In C++, vectors are one type of dynamically-allocated container from the standard template library (STL).

Moving from Java to C++ Just like all other C++ objects, vectors are values. If you assign one vector to another, all elements are copied. Contrast that with the situation in Java. In Java, an array variable is a reference to the array. Making a copy of the variable just yields a second reference to the same array.

Vector space model Vector space model or term vector model is an algebraic model for representing text documents (and any objects, in general) as vectors of identifiers, such as, for example, index terms. It is used in information filtering, information retrieval, indexing and relevancy rankings.f words are chosen to be the terms, the dimensionality of the vector is the number of words in the vocabulary (the number of distinct words occurring in the corpus). Vector operations can be used to compare documents with queries.

- Vector (molecular biology) In molecular cloning, a vector is a DNA molecule used as a vehicle to artificially carry foreign genetic material into another cell, where it can be replicated and/or expressed (e.g.- plasmid, cosmic, Lambda phages). A vector containing foreign DNA is termed recombinant DNA. The four major types of vectors are plasmids, viral vectors, cosmids, and artificial chromosomes. Of these, the most commonly used vectors are plasmids.

- A scalar is a single force or quantity that is independent of other forces, such as speed. Speed can be 45 m/s or 60 mph. A vector is something that involves two forces, such …as velocity which is speed AND direction. For example, velocity can be 5 m/s North. 1 person found this useful.

The Gradient The gradient is a vector operation which operates on a scalar function to produce a vector whose magnitude is the maximum rate of change of the function at the point of the gradient and which is pointed in the direction of that maximum rate of change. In rectangular coordinates the gradient of function f(x,y,z) is:

- In mathematics, a matrix (plural matrices) is a rectangular array —of numbers, symbols, or expressions, arranged in rows and columns —that is interpreted and manipulated in certain prescribed ways.atrices which have a single row are called row vectors, and those which have a single column are called column vectors. A matrix which has the same number of rows and columns is called a square matrix. A matrix with an infinite number of rows or columns (or both) is called an infinite matrix.

Scalar (mathematics) Its coordinates x and y are scalars, as is its length, but v is not a scalar. A scalar is an element of a field which is used to define a vector space. A quantity described by multiple scalars, such as having both direction and magnitude, is called a vector.

What is the difference between raster and vector data? Vector data are excellent for capturing and storing spatial details, while raster data are well suited for capturing, storing, and analyzing data such as elevation, temperature, soil pH, etc. that vary continuously from location to location. Raster data formats also are used to store aerial and satellite imagery.

Linear algebra for game developers ~ part 1 In games, vectors are used to store positions, directions, and velocities. The position vector indicates that the man is standing two meters east of the origin, and one meter north. The velocity vector shows that in one minute, the plane moves three kilometers up, and two to the left.

- In vector graphics, the file that results from a graphic artist's work is created and saved as a sequence of vector statements. For example, instead of containing a bit in the file for each bit of a line drawing, a vector graphic file describes a series of points to be connected. One result is a much smaller file.

vector graphics Same as object-oriented graphics, refers to software and hardware that use geometrical formulas to represent images. The other method for representing graphical images is through bit maps, in which the image is composed of a pattern of dots. This is sometimes called raster graphics. Programs that enable you to create and manipulate vector graphics are called draw programs, whereas programs that manipulated bit-mapped images are called paint programs.
