Hello all As the title states I'm having trouble graphing my for loop, it should be simple but I'm having a hard time plotting the solution. Any help is greatly appreciated, thanks!

k_f = 1; %Miscelaneous-effects factor
z_a = 2.236%Found in table A-10 and table 6-5
k_e = 1-0.08*z_a %Reliability factor
k_d = 1 %Temperature factor table 6-4

k_b = .879*d^(-0.178)
a = 24.4 %table 6-2

S_ut = 43 %table A-20
k_a = a*S_ut^(b) %surface factor
Sp_e = 0.5*S_ut
S_e = k_a*k_b*k_c*k_d*k_e*k_f*Sp_e
N = 1 ;%estimated number of cycles
while N<10^5
N = N+100
S_f = a*N^b
end
plot(S_f, N)
