An integer multiple a function

I want the code run with 5 different graph on loop. But the result is just one. Can anyone help me please?

load ecg_hw2.mat;

n = [4:0.01:4];

N = [2 4 8 16 32];

b = 1./N;

ye = cell(size(b));

t = 1/200;

T2 = 0:t:1000;

h = dirac(n);

idx = h == Inf;

h(idx) = 1;

for i = numel(b);

ye{i} = b(i)*(conv(ecg,h));

figure (4);

subplot(6,1,i);

plot(ye{i});

end

I forgot the value of n, just updated

n isn't defined. I'm assuming that's T2?

load ecg_hw2.mat;

N = [2 4 8 16 32];
b = 1./N;
ye = cell(size(b));
t = 1/200;
T2 = 0:t:1000;
h = dirac(T2);
idx = h == Inf;
h(idx) = 1;

for i = 1:numel(b)
    ye{i} = b(i)*(conv(ecg,h));
    %figure(4);
    subplot(5,1,i);
    plot(ye{i});
end

My code is exactly like you, but my result just show up 1 graph. I dont know why, can you hep me plese?

I dont know the value of n. I took it 200.

A=load('ecg_hw2.mat');
ecg=A.ecg ;
N = [2 4 8 16 32];
b = 1./N;
ye = cell(size(b));
t = 1/200;
T2 = 0:t:1000;
n = [4:0.01:4];
h = dirac(n);
idx  = h == Inf;
h(idx) = 1;
for i = 1:numel(b);
ye{i} = b(i)*(conv(ecg,h));
figure (4);
subplot(3,2,i);
plot(ye{i})
end

My code is exactly like you, but I dont know why I have 1 graph on figure, it must be 5 plots. Can you help me please?

[Arif Hoq]

in your code you forgot to start indexing from 1(look at herein your code: for i = numel(b)). that's why you are getting a single plot i guess.You need a range of indices. I have updated the code.

I really appreciate you. I cant believe I forget very basic matlab
