how to convert from table to time in matlab

To convert a table variable containing date and time information to a MATLAB datetime objects, you can use the datetime function.

Here is an example:

main.m
% Create a sample table
t = table({'2020-10-01 11:30:00'; '2020-10-01 12:30:00'; '2020-10-01 13:30:00'}, ...
          [1; 2; 3], ...
          {'Red'; 'Green'; 'Blue'}, ...
          'VariableNames', {'DateTime', 'ID', 'Color'});

% Convert the DateTime variable to a datetime array
dt = datetime(t.DateTime, 'InputFormat', 'yyyy-MM-dd HH:mm:ss');

% Add the datetime array to the table
t.DateTime = dt;
405 chars
12 lines

In this example, we have a table t with three variables: DateTime, ID, and Color. The DateTime variable is a character array containing date and time information in the format 'yyyy-MM-dd HH:mm:ss'.

We use the datetime function to convert the DateTime variable to a datetime array, and then assign it back to the DateTime variable in the table.

Note that we specify the input date format as 'yyyy-MM-dd HH:mm:ss' using the InputFormat parameter, which matches the format of the DateTime variable in the table.
