Gaussian equation

  1. Feb 11, 2008 #1
    Hi every body,

    I need help how to understand the Gaussian equation.
    For what we can use it i practise.
    I saw it in many things used but I have a problem to understand it.

    Thanks

    Hi,

    Gauss' name was all over the place, so which equation do you mean exactly? I'm guessing you mean a gaussian function such as:

    [tex]f(x)=Ce^{-kx^2}[/tex]

    Is that what you mean?

    Yes it is true I'm meaning for tha function which Mr. Mattson mentioned, this is the basic gaussian function.
    I tried to find the meaning in wikipedia but it was not easy, if somebody can explain it in shortly with one example.
    Thank you.

    citing wiki: "The parameter a is the height of the Gaussian peak, b is the position of the center of the peak, and c controls the width of the "bump"."

    You can just play around with all these parameters in your graph-calculator or Matlab or similar.

    Thank you, for your reply but I can understand the meaning of the variables, also I can solve the equation but my question is:
    I'm an electrical engineer, and I got the meaning but not in total. I want to know with any example in practise, let say what it can describe.

    The wiki article points out some of its uses.

    You posted this in HW-help forum, do you have an exercices that you need help with?

    Very general questions have their answers on the internet and/or textbooks.
