time average of every 100 samples

hello all,

I have 4000 samples of data, and I want to take time average of every 100 or 99 samples and put the result in 100th position of another array.

Thanks in Advance.

Thanks for quick replies, but I do not want to reshape my vector. I think I should add zeros in between and make the result after every 100 samples.

huh? If you do what I did, your vector is not reshaped outside of the calculation of the averages. the averages is what you're looking for per your description.

Answer 1

[Sean de Wolski]

averages = mean(reshape(x(:),100,[]))

Something like this?

You can do something like this:

x = randn(4000,1);
x1 = reshape(x,100,40);
y = mean(x1);

Now you have the mean of every 100 samples. You can now put those values in another array as you wish.
