What does this syntax mean?

Can you explain to me what does it mean this syntax end-364:end? Thank you

It looks like it would be inside an array and mean that it's taking the last 365 elements of the array. E.g.

last365elements = data(end-364:end);

You can index and array with end. End is basically just the length of your variable. So this is saying "index from the 365th from last to the last element of my array."

Example:

 >>A = 1:10;
 >>A(end-3:end)

 ans =
      7     8     9    10
