using a value from table based on the current time

So I have a table that include a columne for date, a column for time and a column for Rain intensity value

my question is if there is anyway to use the rain intensity value (of the current real time) in an equation in matlab

for example lets say that the date and time right now is 1st of march 10:15 AM then i want to use the value of rain intensity of the date 1st of march and time 10:15 AM from the excel table in a specific equation .

Hi @Graduation Project,

In order to utilize the rain intensity value from a table for the current real-time date and time in MATLAB, first ensure the table is imported into MATLAB using 'readtable' function. After obtaining the current date and time using the 'datetime' function, date, month of the year and time can be obtained separately leveraging 'datestr' function. Refer to the following documentation of 'datestr' to know more about different date formats: https://www.mathworks.com/help/matlab/ref/datetime.datestr.html

Here is a code snippet explaining the functionality

% Get the current date and time
currentDateTime = datetime('now');

% Extract and format the desired components
dateStr = datestr(currentDateTime, 'dd');
monthStr = datestr(currentDateTime, 'mmmm');
hourStr = datestr(currentDateTime, 'HH');
minStr = datestr(currentDateTime, 'MM');
disp("Day: " + dateStr + " Month: " + monthStr + " Hour: " + hourStr + " Min: " + minStr);

Day: 28 Month: February Hour: 06 Min: 17

Finally logical indexing can be used to compare the date and time columns to the current date and time. Once the specific row is identified, extract the rain intensity value and use it in the desired equation.
