Hi! I need your help. Actually I can do this in excel, but I am curious about how to do it in Matlab. I attach the picture in excel about the mathematical operation I want to do. I want to calculate the duration in minutes by substracting one cell with previous cell and multiply it by 24*60. I also want to do it consecutively until the last row. Do you know how to do it with matlab code? Suppose I have a table with three variables, the first one for duration, the second one for rainfall intensity (mm/min) and the third one for the duration (minutes) which I want to calculate. Could you please help me? Thank you very much in advance.

diff() will give you the difference between rows of each column in your table, t. For example:
dDate = diff(t.Dates);
dt = diff(t.Rainfall);
dd = diff(t.duration);
