for n = 1:100
PP = P(n,1);
x = n;
plot(x, P);
hold on
end
The code above doesn't work. Please help fix it and make sure to display three consecutive values that have the largest sum.

I don't you are summing anything

P = randn(1,8);
display(P);
P = 1×8
0.9215 -0.2768 0.7009 1.2080 0.0836 -0.7582 1.4873 -0.3553
Npts = 3;
display(P(idx+(0:Npts-1)));
0.7009 1.2080 0.0836

Hi, the followed code could be easier to understand:
P = rand(100,1);
mx = -Inf;
for i = 1:98
mx = max(mx, sum(P(i:i+2)));
end
mx
