title: RBF neural network parameters size
body: <p>I want to define a function approximation by RBF neural network in MATLAB.</p>
  
  <p>RBF needs there parameters as "unit centers", "sigma" and "weight". I have a dataset by 1000 records and 10 features.</p>
  
  <p>first question: these three parameters should be in an array format? or can be in matrix format?</p>
  
  <p>second question: I defined "unit centers" by k-means clustering over dataset. This is three cluster centers.
  For "sigma" and "weight" parameters, i should define a matrix same as the "unit centers" size?</p>
  
  <p>unit centers are matrix by 3*10 size. Other two RBF parameters should assign in 3in10 size? Or can i define them in 1in10 or 2in10 size?</p>
