how to pull time column data from excel into matlab in matlab in matlab

To pull time column data from Excel into Matlab, you can use the "xlsread" function to read the data in the Excel file and the "datetime" function to convert the time values to Matlab datetime format. Here is an example:

main.m
% Define the Excel file name and sheet name:
filename = 'example.xlsx';
sheetname = 'Sheet1';

% Read the data from the Excel file:
[num, txt, raw] = xlsread(filename, sheetname);

% Get the time data as a cell array of strings:
time_str = raw(2:end, 1);

% Convert the time data to Matlab datetime format:
time = datetime(time_str, 'Format', 'HH:mm:ss');
356 chars
13 lines

In this example, the first column of data in the Excel sheet is assumed to be the time data, and the data starts from the second row (i.e., row 1 is assumed to be the header). The "time_str" variable is a cell array of strings, where each string represents a time value in the format "HH:mm:ss". The "datetime" function is then used to convert these strings to Matlab datetime format, using the "Format" option to specify the input format.
