Hello Community. Here im trying to find the rho_a using the Newton Raphson Method. But im new to MATLAB and can't figure it out by myself.
Here's my Code;
clc; clear all
f_o =0.527;
f_i = 0.506;
Z = 8;
D_w = 10.32;
rho_0 = (f_i+f_o-1)*D_w;
F_a =2600;
alpha_no = 7.61;
C_delta = 7.14*10^5;
syms rho_a
f = @(rho_a) ((sin(alpha_no)+rho_a)/((cos(alpha_no)^2+(sin(alpha_no)+rho_a)^2))^1/2)*(((cos(alpha_no)^2+(sin(alpha_no)+rho_a)^2))^1/2)-1^3/2;
fd = diff(f(rho_a));
rho_a = 10^-6;
for i=1:100000
rho_a = rho_a - f./fd;
if abs(f-LHS/LHS)<=10^-4
