I'm not sure with that, i download the data from the link below:
personally, I feel they should be in pcd file, somehow the downloaded file is bin.
I have tried
fid = fopen('n008-2018-08-01-15-16-36-0400__LIDAR_TOP__1533151061547455.pcd.bin', 'r');
data = fread(fid, '*int16');
fclose(fid);
I get a series of numeric data (one column), should i restructure it to 3 coloumns to represent x,y,z? Any insight?

Actually after reading the data using fread it will be reshaped to required dimension using reshape. To achieve this format of the file should be known.

Is this fine?
fid = fopen('n008-2018-08-01-15-16-36-0400__LIDAR_TOP__1533151061547455.pcd.bin', 'r');
data = fread(fid,'single');
fclose(fid);
data = reshape(data,[],2) ;
plot(data(:,1),data(:,2),'.r')

Read the data as a float using fread.
For nusences dataset each point in the point cloud contains 5 floats. reshape the data and use pcshow for display.
