There are two aspects of the problem.
  1. How do I read a tenv3 data file? The source file can be found here.
  2. I wish to extract the data under the 4th, 9th, 11th, and 13th column, such that the first row of the extracted data should read,
" 54847 -1.187879 0.058425 0.879526".
Also can these be stored in the form of an excel file or a txt file?
Please help.

Hi @Vikash Pandey,
Unfortunately, MATLAB does not recognize the '.tenv3' file extension. However, a workaround is renaming the file extension to '.txt', which enables the usage of MATLAB's standard commands to manipulate the table and achieve the intended results.
Below is an illustrative example on how to manage a '.txt' file format:
data = readmatrix('your_data_file.txt');
% Extract the 4th, 9th, 11th, and 13th columns
extracted_data = data(:, [4, 9, 11, 13]);
% Display the first row of the extracted data
disp(extracted_data(1, :));
To save the extracted data to an Excel file, you can use the writematrix function:
% Save the extracted data to an Excel file
writematrix(extracted_data, 'extracted_data.xlsx');
And to save it as a text file:
% Save the extracted data to a text file
writematrix(extracted_data, 'extracted_data.txt', 'Delimiter', ' ');

@Vikash Pandey
writematrix(Extracted_Data, '~/Desktop/Work/Extracted_Data.xlsx')
for Mac and Linux.
For Windows, finding the Desktop folder is a bit more complicated.
profold = fullfile(getenv('USERPROFILE'), 'Desktop', 'Work');
writematrix(Extracted_Data, fullfile(profold, 'Extracted_Data.xlsx'));
However I do not promise that this will work if the Desktop has been moved to OneDrive
