Hello everyone,
I am trying to get output as 2*4 matrix. You can find my simple code as:
t=2;
kr=2;
s=[0;0];
R=[2 3; 3 4];
D=[4 5; 5 6];
s1=zeros(kr,t);
for i=1:kr
for j=1:t
s1(i,j)=max(s(i)-R(i,j),0)+D(i,j);
s(i)=s1(i,j);
end
end
s2=zeros(kr,t);
for i=1:kr
for j=1:t
s2(i,j)=max(s(i)-R(i,j),0)+D(i,j);
s(i)=s2(i,j)
end
end
S=[s1 s2]; % final output
I would like to use a single loop rather than repeating the loop for and to get this final output of S (2*4).. It's okay for only s1 and s2 but I have . Any help is appreciated.
Regards

t=2;
kr=2;
s=[0;0];
R=[2 3; 3 4];
D=[4 5; 5 6];
s1=zeros(kr,t);
S = [];
for n = 1:100
for i=1:kr
for j=1:t
s1(i,j)=max(s(i)-R(i,j),0)+D(i,j);
s(i)=s1(i,j);
end
end
S = [S s1];
end
does this do what you want?
