What is a matrix?

The matrix is ​​a rather polysemantic word thatcame to our speech from German. This word can be found in the field of mathematics, engineering and electronics and even in the film industry. But first things first. So, what is a matrix?

Mathematical Matrices

In mathematics, the term "matrix" meansA mathematical object that is a rectangular table consisting of integers or fractional numbers. In fact, this is a collection of rows and columns, at the intersection of which the elements of the matrix are located. The size of the matrix is ​​determined by the number of rows and columns. What are matrices for mathematics? In general, they are used for the convenient and compact arrangement of systems of linear equations. With such a record, the number of rows of the matrix will be equal to the number of equations in the system, and the columns will correspond to the unknowns. Thus, the search for unknowns is simplified. With matrices, you can perform algebraic operations: multiplication, addition, multiplication by a matrix of a vector and a scalar.

Matrixes in cameras

Very often when buying a digital cameraSales consultants draw our attention to the matrix. What is the matrix in the camera? It is a microchip, which consists of light-sensitive elements, they are called photodiodes. The matrix is ​​an integral part of any digital device intended for shooting. In fact, the matrix converts the visible optical image into an electronic signal, that is, directly into digital data. The photomatrix divides the resulting image into pieces called pixels. Accordingly, the more pixels in the camera, the more accurate the transmission of the original image.

Matrices in displays and video equipment

It is difficult to overestimate what the matrix inliquid crystal displays. There are monitors and panels, the device of which includes various matrices. The technology of In-Plane Switching, or as it is called ips matrix, was developed in 1996. At first, it had a number of drawbacks, but at the present time it is thanks to it on the monitor that we see a rich palette of tens of millions of colors. Another advantage of ips matrix is ​​the transfer of black color, ideal for the human eye. Almost all modern LCD-panels are equipped with an ips matrix.

The Matrix in Fantasy

Probably everyone heard about the movie "The Matrix". This is a sensational science fiction thriller. It is one of the theories that the whole of our world is a matrix. The picture depicts a future in which everything that people see is just a simulation, an illusion. This was done by intelligent machines in order to pacify human consciousness and enslave it. Simultaneously, machines use human heat, converting it into energy.

Polygraphy and matrices

If you take the history of the development of the printing business, you cansay what the matrix means in this sphere of human activity. Man always wanted to see the results of his activities on paper. At some point in time people were puzzled by the problem of reducing the size of printing equipment. At the same time, a matrix for printing was developed. The idea was that any image would consist of a set of dots or pixels. This idea was realized due to the use of a printing head with needles. Today, this technology is developed so that the use of dot-matrix printers is one of the most economical.
