Hi everyone,

I have one cell vector with the date in this format {YY-MM-DD}, I would like to obtain three different vectors that contain 'YY', 'MM', 'DD'. I tried to convert this in str and using strsplit command but it doesn't work. Is there someone that can help me?? Thanks.

date =
  1472×1 cell array
    {'1985-01-01'}
    {'1985-01-01'}
    {'1985-01-01'}
    {'1985-01-01'}
    {'1985-01-02'}
    {'1985-01-02'}
    {'1985-01-02'}
    {'1985-01-02'}
    {'1985-01-03'}
    {'1985-01-03'}

在 MATLAB Online 中打开

Using datetime:

>> DT = datetime(date,'InputFormat','yyyy-MM-dd');
>> DT.Year
ans =
        1985
        1985
        1985
        1985
        1985
        1985
        1985
        1985
        1985
        1985
>> DT.Month
ans =
     1
     1
     1
     1
     1
     1
     1
     1
     1
     1
>> DT.Day
ans =
     1
     1
     1
     1
     2
     2
     2
     2
     3
     3

Or using regexp:

>> tkn = regexp(date,'^(\d+)-(\d+)-(\d+)$','tokens','once');
>> tkn = vertcat(tkn{:});
>> Y = tkn(:,1)
Y = 
    '1985'
    '1985'
    '1985'
    '1985'
    '1985'
    '1985'
    '1985'
    '1985'
    '1985'
    '1985'
>> M = tkn(:,2)
M = 
    '01'
    '01'
    '01'
    '01'
    '01'
    '01'
    '01'
    '01'
    '01'
    '01'
>> D = tkn(:,3)
D = 
    '01'
    '01'
    '01'
    '01'
    '02'
    '02'
    '02'
    '02'
    '03'
    '03'
