What does gamma mean and what is the gamma function?

It's a mathematical term.

(x) is called the gamma function.

It is defined in terms of an integral formula, not a primary letter filial piety number.

The gamma function has properties: (x+1)=x (x), 0)=1, (1 2)= a positive integer against silver.

n, there is (n+1)=n! 11

Expression: (a)=

x^(a-1)]*e^(-x)]dx

Skillful grip application in MATLABIt represents the factorial of an integer in the range n-1 to 0.

The formula is: gamma(n)=(n-1)*(n-2)*2*1 For example: gamma(6)=5*4*3*2*1ans=120

is factorial. A class of functions that extend on real and complex numbers. This function is used in analytical, generalized muffiness rate theory.

There are important applications in partial differential equations and combinatorics. Closely related to this function is the beta function, also known as the first type of Euler integral. It can be used to quickly calculate the same gamma function.

Gamma introduced

Gamma is used in the field of optics. Each pixel in a digital image has a certain level of brightness, i.e. from black (0) to white. These pixel values are the information that is fed into the computer's display blocker.

However, due to technical limitations, Flat Screen (CRT) displays can only output these values in a non-linear manner, and most CRT displays are unadjusted.

All have a gamma value.

The meaning of this is that if the brightness of a pixel is, without the intervention of a color management application (*) it will output only the brightness on the display.

Gamma has different meanings in different contextsOne means a transformation of the original signal, the other means a family of metric parameters for this transformation, and may also represent a specific concept of display gamma, system gamma, and file gamma.

1. Display gamma

It is the physical property of the display, fixed, unchanging, and non-correctable. Display gamma has different meanings in different contexts, one is to refer to the distortion of the output image of the display to the input signal, and the other refers to the specific value of this distortion.

One of the applications of gamma correction is the calculation formula of lightness and grayscale.

2. File gamma

For a given digital photo file, this gamma is a fixed value according to the relevant standard specifications, and it is not necessary to correct it. If, for some special purpose, the gamma value of a digital photo file must be changed, this change cannot be called a "correction", but rather a "transformation".

3. System gamma

The transformation represented by the system gamma is a transformation of the computer system after reading the ** digital file, before it is output to the monitor, for the Windows system it exists in the graphics card, it is adjustable and correctable.

Gamma is a Chinese pinyin word that is pronounced gāmǎ. Among them, the tone of gā is the first tone, and the tone of mǎ is the light tone.

Gamma is a symbol from the Greek alphabet and is denoted as . In physics, gamma generally refers to a type of radiation in the electromagnetic pre-liquid spectrum, known as gamma rays. Gamma rays are a kind of high-energy electromagnetic waves with strong penetrating and lethal power, so they have a wide range of applications in medicine, industry, and scientific research.

In addition to gamma rays in physics, gamma is also important in mathematics, computer science, and other fields. In mathematics, the gamma function is a special type of function that has a wide range of applications in the complex plane. In computer science, a gamma tree is a data structure that is used to solve some graph theory problems.

In conclusion, gamma is an important word that has different meanings and applications in different fields. Whether in physics, mathematics, computer science, or other fields, it is very useful to understand the meaning and pronunciation of gamma. <>
