Hello to everybody, my goal is to get a matrix of numbers starting from a timeseries which was created by the command "datetime".

a=datetime(1981,1,1);
b=datetime(1983,31,1);
t1=a:b;
t2=datetime(t1,'Format','yyyy-M-d');

So t2 will be a (1643x1) datetime vector in the format [1981-1-1 ; 1981-1-2 ; 1981-1-3 ;......], i'd really like to trasform that vector into a numerical matrix done in this format:

[1981,1,1 ;1981,1,2 ;1981,1,3 ;.....].

I hope that my question is clear. Thank you!

在 MATLAB Online 中打开

M = [t2.Year(:),t2.Month(:),t2.Day(:)]
M = 1643×3
        1981           1           1
        1981           1           2
        1981           1           3
        1981           1           4
        1981           1           5
        1981           1           6
        1981           1           7
        1981           1           8
        1981           1           9
        1981           1          10

or use the first three columns:

M = datevec(t2)
M = 1643×6
        1981           1           1           0           0           0
        1981           1           2           0           0           0
        1981           1           3           0           0           0
        1981           1           4           0           0           0
        1981           1           5           0           0           0
        1981           1           6           0           0           0
        1981           1           7           0           0           0
        1981           1           8           0           0           0
        1981           1           9           0           0           0
        1981           1          10           0           0           0
