Newton's Method to Solve Equation
1 view (last 30 days)
I trying to write a code to solve an equation using newton's method and given three inputs.
So far I have
syms L h T g
f_L = L-g*T*T/(2*pi)*tanh(2*pi*h/L)
Df = diff(f_L,L)
The variable Df is in symbolic form but I need to convert it to numeric. Any ideas how to do this?
