storing a code in a for loop

hi, could anyone help me here? i've been given a task to store the code attached into one big for loop which executes the code and runs it all in one go then gives the image from the frames in the code. How can i do this?

clc
clear all

f=1;
N = 330;
M = nan(156,206,N);
for ii = 1:N
    M(:,:,ii) = load(sprintf('frames_%d.txt',ii-1));
end
b=load('timestamp.txt');

for i=2:N
    b(1)=0;
b(i)=b(i)+b(i-1);
end

c=b(1:N);

% b=b';

% MM=M(:,:,1:length(t));
% t=(0:2970)/33;
% MM=M(:,:,1:length(t));
% f=2;
% for i=1:156
%     for j=1:207
%         I(i,j,:)=squeeze(MM(i,j,:))'.*sin(2*pi*f.*t);
%         Q(i,j,:)=squeeze(MM(i,j,:))'.*cos(2*pi*f.*t);
%     end
% end


for i=1:N
    
        I(:,:,i)=squeeze(M(:,:,i))'.*sin(2*pi*f.*c(i));
        Q(:,:,i)=squeeze(M(:,:,i))'.*cos(2*pi*f.*c(i));
end

II=sum(I,3);

QQ=sum(Q,3);
Amp=sqrt(II.^2+QQ.^2);dlk
