高斯函数 Gaussian function

(重定向自Error Curve)
用期望值及方差作为参数表示的高斯曲线(参见正态分布)
Forma tridimensional.
Histograma y la curva normal

高斯函数的形式为

f(x) = a e^{-(x-b)^2/2c^2}

的函数。其中abc为实数常数,且a > 0.

c = 2的高斯函数是傅立叶变换的特征函数。这就意味着高斯函数的傅立叶变换不仅仅是另一个高斯函数,而且是进行傅立叶变换的函数的标量倍。

高斯函数属于初等函数,但它没有初等不定积分。但是仍然可以在整个实数轴上计算它的广义积分(参见高斯积分):

\int_{-\infty}^\infty e^{-ax^2}\,dx=\sqrt{\frac{\pi}{a}}

Gaussian function 高斯函数

(重定向自Error Curve)
Gaussian curve with a 2-dimensional domain

In mathematics, a Gaussian function, often simply referred to as a Gaussian, is a function of the form:

for arbitrary real constants a, b and c. It is named after the mathematician Carl Friedrich Gauss.

The graph of a Gaussian is a characteristic symmetric "bell curve" shape. The parameter a is the height of the curve's peak, b is the position of the center of the peak and c (the standard deviation, sometimes called the Gaussian RMS width) controls the width of the "bell".
