What are Matices used for besides math.?

Question

I need to know what matrices are used for. how they are used in everyday things... Besides Math. I don't need to know how to solve them or anything (i know how to do that) just how they are used.

Answer 1

matrices find their application in all walks of life,not alone in mathematice
for representing data as an array the matrices are used

Cryptography involves encrypting data so that a third party can not intercept and read the data.

In the early days of satellite television, the video signals weren't encrypted and anyone with a satellite dish could watch whatever was being shown. Well, this didn't work because all of the networks using satellites didn't want the satellite dish owners to be able to receive their satellite feed for no cost while cable subscribers had to pay for the channel, they were losing money. So, they started encrypting the video signal with a system called Videocipher (later replaced by Videocipher II).

What the Videocipher encryption system did was to convert the signal into digital form, encrypt it, and send the data over the satellite. If the satellite dish owner had a Videocipher box, and paid for the channel, then the box would descramble (unencrypt) the signal and return it to its original, useful form.

This was done by using a key that was invertible. It was very important that they key be invertible, or there would be no way to return the encrypted data to its original form.

The same thing can be done using matrices

Answer 2

Applications--

Transportation

If one is given a list of cities (or destinations, nodes, etc) and is told that there are flights (or roads, connections, etc) from city a to city b, then one can build a square matrix with the cities indexing each side of the matrix. So each entry M[a,b] = 1 if there is a connection from a to b. If there is a reverse connection from b to a then also M[b,a] = 1. In many instances the connection a to b might not be bidirectional, ie M[a,b] = 1 does not necessarily imply that M[b,a] = 1. If there is no connection from a to b then M[a,b] = 0.

By multiplying the matrix M by itself to obtain M2, then M2 will indicate if two cities a and b can be reached by 1 or more layovers. That is, if for example M[a,b] = 0, but M2[a,b] = 1, then a and b are connected via a third city c, a layover between a and b. If M2[a,b] = n then a and b are connected via n layovers.

Answer 3

A matrix (plural matrices) is nothing more than array of information. Often we call such an array a "table."

The fundamental unit of a matrix is the element. Each element is located in the table (matrix) by its row, column number or position. Thus, element (2,3) would be the element where row 2 intersects column 3.

A table of baseball batting averages is an example of a non-math matrix. The first column is typically a list of each ball player's name on the team. The second column is usually made up of each corresponding player's batting average.

Stock quotes are typically given as a table in the newspaper. Here you might find the following columns: Stock Symbol; Last Price; Close Price; Change. Each row would contain the column indicated information for a single common stock.

Anywhere we need to organize a lot of information, we generally can use the table format to do it. In math, we call that format a matrix and give it specific rules to operate by. Those rules are the basis for a branch of math called matrix or linear algebra.

One of the interesting rules in matrix algebra is that AB <> BA in general. Which is quite different from ab = ba, which is true for ordinary, scalar variables.

Matrix algebra is also applied to vectors analysis or algebra. For example, each column in a matrix might represent the points on a directed line (e.g., an arrow) called a vector.

Answer 4

They are used for organizing data

ex:
seniors juniors sophmores freshman
male 100 273 322 221

female 92 341 340 210
your matrice:

100 273 322 221

92 341 340 210

Answer 5

Matrices are basically a technique to store data.Matrices become very much useful when the amount of data becomes huge.So use of matrices,you can gues,is not limited to mathematics.Wherever there is something to do with data,we use matrix.For example,during programming,we use matrix.In Physics,matrices are used for descrbing electron behavior.In chemistry, there is a branch called group theory where these matrices are used for designating rotation of atoms.Even in Logic matrices are used to store the truth-values of the statements.So you can see there are infinite application of matrices apart from mathematics

Answer 6

They are used broadly in Higher engineering physics, Higher physical Chemistry & Business & economy subjects.
Actually there is a level in higher education, where Physics, Chemistry & Math merge with each other.
Matrix is a very elaborated subject,& There is a branch of Higher math named linear algebra consisting of mainlt matrices & determinants. So its impossible to give a desctiption of it in such short (especially when I dont know about your education,because what seems simple to a engineering 4th year student, may seem choking for a 11th grade student) & you have also mentioned you more or less have an idea about the topic.

Answer 7

A lot of fields like physics, chemistry, business & management involve the solution of a system of linear equations.

The method of solving involves the use of matrices

Answer 8

Woh dont take matrices lightly... It is very very important part of information technology. Mainly it is used in image processing. Without matrix u cant think of image or photos......

Answer 9

You won't find them used in everyday applications, but they play a fundamental role in, for example, business, because they are used to describe optimization problems such as how to maximize profit.

Answer 10

A big portion of precalculus is devoted to learning "identities" involving the sin cos tan sec csc cot functions, and 3 of those are proven with the pythag. thm.
