Hi!
I am doing some numerical calculations recently. I need to calculate the functional derivative. eg. functional :
[tex]n(\rho)=\int dr'r'\rho(r')f(r,r')[/tex]
it need to calculate:
[tex]\frac{\delta n(r)}{\delta\rho(r')}[/tex]
I think the derivative is r'f(r,r'). Is this right?
Thanks very much!
