MATLAB 2011a introduces the functionrngwhich allows you to control random number generation much more easily. For example. in older versions of MATLAB you would have to do the following to reseed the default random number stream to something based upon the system time. RandStream.setDefaultStream(...
First, how many points determine a plane? THREE. That is, if you have a surface z(x,y), then EXACTLY 3 points are needed to determine a plane. And if you have 4 points, there will in general be no perfectly planar surface that passes through all...
