body: <p>I did some work and finally i got a data that its shape looked like sinc function and i tried to search how to fitting graph to sinc function using by numpy and i found this:</p>
  
  <p><a href="https://stackoverflow.com/questions/22950301/fitting-a-variable-sinc-function-in-python">Fitting a variable Sinc function in python</a></p>
  
  <p>It's good that i found it but i think why it look quite complicated?</p>
  
  <p>Can you give me more friendly way to fitting graph that give me a curve like sinc function?</p>
