Answer 1

Since the question is tagged with MATLAB, I explain it in that platform: First, you need to load your input data matrix:

load('YourPointCloud.mat');

Then, use pcwrite function to save as *.pcd format:

pcwrite(ptCloud,'object3d.pcd','Encoding','ascii');

To try your result, you can load the saved file with:

pc = pcread('object3d.pcd');

Finally, visualise it with:

pcshow(pc);
