Matrix dimensions must agree.

Hello everyone, can you please help me with this problem? I currently in my project's for Iterative Method. But I can't run the coding because of this problem.
P=(Lamda-beta)./(gamma*2);
Attached below is my full coding, can you guys help me?
clear clc;
% n all alpha beta gamma min max
d=[1 550 8.1000 0.00028 0 680

Iteration=i;
Lamda=8.35; % assume lambda L(i,1)=Lamda;
while abs(DelP)> 0.00001
P=(Lamda-beta)./(gamma*2);
P=min(P,Pmax); %p=ph if pmax<p//p>pmax //pick pmax bila pmax kecil dri p
P=max(P,Pmin); %p=pl if pmin>p//p<pmin
DelP=Pd-sum(P); Lamda=Lamda+DelP/(sum(1./(2*gamma)));
costI(:,i)=alpha+(beta.*P)+(gamma.*P.*P);
totalCost_iteration(i,1)=sum(costI(:,i));
Iteration(i,1)=i;
Lamda(i,1)=Lamda;
i=i+1;
end

ylabel('Cost(RM/h)')

Omg, thank you so much. I'm still wondering which part of it is wrong.
but thank you so much, Sir. Thank you.

This was the line causing the probem
Lamda(i,1)=Lamda;
