title: How to generate Gaussian Noise in Java?
body: <p>I am looking for a Gaussian Noise generator that takes in 2 parameters: mean and variance, and then generates the Gaussian Noise.</p>
  
  <p>During the searching, I find quite a number of such generators for images. However, what I want is a generic generator. I wish to do something like:</p>
  
  <pre><code>myGaussianNoiseGenerator = new GaussianNoiseGenerator(mean, variance);
  mySignalWithNoise = mySignal + myGaussianNoiseGenerator.generate();
  </code></pre>
  
  <p>How may I do this?</p>
