Hi,
I have a 527040 x 4 table
I need a new table, that gives me for each i = size(array,1) the sum of the next delta of rows
So for example set delta = 4
row 1 should be sum of rows 2 to 5
row 2 should be sum of rows 3 to 6 and so on
me biggest problem now is, i dont know what to do at the end of my input table if the number of remaining rows is smaller then my delta. I think the best idea is to just cut them out....
any ideas?
I use MATLAB R2019a for students
