One of my earliest favorites was a spy detective game. And I doubt you are the only one who has never played. I used to wonder how detectives decoded secret messages as a kid. And I was always curious.
When I grow older, I can decode the message. So, what? Cryptography is one of the applications of linear algebra. I’ve included the intriguing uses of linear algebra below. So, let’s get into the nitty-gritty of one more math
What is algebra?
Vector spaces, infinite dimensions, and linear mapping between them are all part of this discipline of mathematics.
Vectors and matrices are used to represent linear algebra equations. Applied and pure mathematics both require linear algebra.
LINEAR ALGEBRA RELATES TO LINE It means you can use arithmetic on numbers’ columns (arrays) and numbers’ vectors (matrices). These matrices are made for new number arrays and columns.
For example, the vector space axioms are relaxed using the abstract algebra method. The infinite-dimensional vector space functional analysis.
However, linear algebra aids in solving differential equations using linear systems.
These include physics, computer science, analytic geometry, natural sciences, computer animation and social sciences (particularly in economics).
Linear algebra is a well-developed theory used to approximate non-linear mathematical models.
What is the use of linear algebra?
It is the study of secret message decoding and encoding. Solid encryption can be used in electronic transactions and communications. Decoding/encoding the messages uses modular arithmetic. Simpler encoding methods use matrix transformations.
As stated previously, linear algebra is employed to decrypt the hidden message (a cryptography method).
Let’s see an example.
To encrypt short secret communications, assign a number to each alphabetical letter.
Then, arrange the text numbers in a square matrix (taken as A).
Then fill the matrix with zeros if the letters number is less than the element number.
PICK A NONSINGULAR SQUARE Matrice To encrypt the message, multiply A by B. Assume matrice B:
A white cat becomes text ”BILA KOCKA” in matrix A:
to encrypt text, use:
To decipher the message, multiply Z by B inverse.
Matrix multiplication is not commutative, hence it must keep the exact product matrix. If you reverse the Z and B inverse matrices, you get:
Now it was “CERNY PSIK” (a variety of black dogs).
It’s another use of linear algebra, which is a mathematical study of choices. The players make these choices while playing. Psychologists employ the social interaction theory to compare the player’s alternatives to other competitors.
Despite its focus on cards, board games, and other competitive games, game theory also applies to military strategy.
Let’s see an example.
It is a simple zero-sum game. A payment matrix is utilized, like in the Prisoner’s Dilemma.
Assume you need to add up the two players’ scores. Each win adds one point to the player’s total, while each loss subtracts one. Tie: no points are subtracted or added.
The payoff matrix will therefore be:
This matrix is skew-symmetric. So the game is symmetrical.
If one player wins, the other loses. If both players tie, the point is not awarded.
It’s a zero-sum game.
The favorable options are rewarded, while the negative options are opposed.
Are there other uses for linear algebra?
Aside from the above uses, linear algebra is utilized in:
Analyzing networks via graphs.
Engineering matrices, like a springs line.
Simplified linear programming optimization
Less squares for regression and probability.
Fourier Series utilized in signal processing.
Equilibrium temperature distributions.
Leontief’s economic models show how outputs, prices, and desires interact.
Using X-ray scans, computed tomography creates a cross-sectional representation of the human body.
Learn about dominant and recessive traits in genetics.
Including data fitting and differential equations.
A fun fact about linear algebra:
Albert Einstein employed linear algebra, a sort of mathematics. He employed tensor calculus and tensors in relativity theory. He also introduced linear algebra notations to physics. It’s called Einstein notation or Einstein summation convention.
Linear algebra is the study of planes, lines, maps, and vector spaces. Thus, it is vital to grasp linear algebra applications. Those are the applications. Understand them well and use linear algebra in real life.
