Hello Gaurav,
For converting a set of ".txt" files containing label information of your lidar data into ".mat" format, you may read the ".txt" files using the "readmatrix" function and then save the data into ".mat" format. For your reference on the same, I am attaching below a sample code snippet:
% Define the folders containing the ".txt" files and ".mat" files
txtFolder = 'path_to_folder_having_txt_files';
matFolder = 'path_to_folder_to_save_mat_files';
% Create a destination folder to save the ".mat" files
if ~exist(matFolder, 'dir')
mkdir(matFolder);
end
txtFiles = dir(fullfile(txtFolder, '*.txt'));
% Loop through each TXT file, read the data, and save it as a MAT file
for i = 1:length(txtFiles)
txtFilePath = fullfile(txtFolder, txtFiles(i).name);
% Read the data from the ".txt" file using "readmatrix" funcion
labelData = readmatrix(txtFilePath);
[~, name, ~] = fileparts(txtFiles(i).name);
matFilePath = fullfile(matFolder, [name, '.mat']);
% Save the label data into a ".mat" file
save(matFilePath, 'labelData');
end
For more information on the "readmatrix" and "save" functions, you may refer the following MathWorks documentation links:

- https://www.mathworks.com/help/matlab/ref/save.html
I hope you find the suggested workaround useful!

Chandrika
