Plotting using a for loop in Matlab and finding the highest three consecutive value, given imported spreadsheet table of 1x100 called 'P'?

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;
[~,idx] = max(movsum(P,Npts,'EndPoints','discard'));
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
