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.
