bessel function derivatives problem
7 views (last 30 days)
i have following equation that contain bessel function :
1- u(r)=j1(r) [1 mean the order and r is Variable(sysm)]
2-w(r)=j0(r)+i0(r) [0 mean the order and r is Variable(sysm)]
i need the the first derivative of the first equation (1 u(r) ) and second derivative of the second equation (2 w(r) )
is there any direct code for this purpose ?
thank a lot for your helps
