You can generate normally-distributed random values with randn. For a point cloud for example, if you have 100 points with x, y, z values, you can create a noise array to add to the point array:

>> gaussNoise=randn(100,3);
>> scatter3(gaussNoise(:,1),gaussNoise(:,2),gaussNoise(:,3))

Thank you Brian for your answer.

I have find this in the matlab documentation fo compleate my research.
