If I have yhe code below, and I want the table to record all my iteration, how to do the table function? Since it's only displaying the last iteration only.
Input Lambda as 9 and Total Power as 450
clc
clear all
P=0;
kanan = input('Masukkan Lambda Awal, Lambda 1 : ')
kiri = 0;
Lmbd = 0;
P = 0;
a = [ 0.0025 8.4 225 ];
b = [ 0.0081 6.3 729 ];
c = [ 0.0025 7.5 400 ];
Total_P = input('Total Power, P : ')
FC1 = 0.8;
FC2 = 1.02;
FC3 = 0.9;
F1 = FC1*a;
F2 = FC2*b;
F3 = FC3*c;
Iterasi = 1;
Lmbd = kanan;
P1 = (Lmbd - F1(2)) / (F1(1)*2);
P2 = (Lmbd - F2(2)) / (F2(1)*2);
P3 = (Lmbd - F3(2)) / (F3(1)*2);
P = P1 + P2 + P3;
while abs(P - Total_P) >= 0.0001
Iterasi = Iterasi + 1;
Lmbd = abs((kanan + kiri) / 2);
P1 = (Lmbd - F1(2)) / (F1(1)*2);
P2 = (Lmbd - F2(2)) / (F2(1)*2);
P3 = (Lmbd - F3(2)) / (F3(1)*2);
P = P1 + P2 + P3;
if P > Total_P
kanan = Lmbd;
end
if P < Total_P
kiri = Lmbd;
end
end
% P1
% P2
% P3
T = table(Iterasi, P1, P2, P3, P, Lmbd);

to record all iteration, you need to store them in loop.
As shown in below code.
clc
clear all
P=0;
TUpdated={};
kanan = input('Masukkan Lambda Awal, Lambda 1 : ')
kiri = 0;
Lmbd = 0;
P = 0;
a = [ 0.0025 8.4 225 ];
b = [ 0.0081 6.3 729 ];
c = [ 0.0025 7.5 400 ];
Total_P = input('Total Power, P : ')
FC1 = 0.8;
FC2 = 1.02;
FC3 = 0.9;
F1 = FC1*a;
F2 = FC2*b;
F3 = FC3*c;
Iterasi = 1;
Lmbd = kanan;
P1 = (Lmbd - F1(2)) / (F1(1)*2);
P2 = (Lmbd - F2(2)) / (F2(1)*2);
P3 = (Lmbd - F3(2)) / (F3(1)*2);
P = P1 + P2 + P3;
while abs(P - Total_P) >= 0.0001
Iterasi = Iterasi + 1;
Lmbd = abs((kanan + kiri) / 2);
P1 = (Lmbd - F1(2)) / (F1(1)*2);
P2 = (Lmbd - F2(2)) / (F2(1)*2);
P3 = (Lmbd - F3(2)) / (F3(1)*2);
P = P1 + P2 + P3;
if P > Total_P
kanan = Lmbd;
end
if P < Total_P
kiri = Lmbd;
end
TUpdated = [TUpdated; table(Iterasi, P1, P2, P3, P, Lmbd)];
end
TUpdated

Thank you Mr. Bhavsar. It solve my question well. I need to learn more about how arrays work in Matlab. The one that impress me is how you store the table using array {}, not matrix [].
