** Normally distributed random numbers and matrices. **

** RANDN(N) is an N-by-N matrix with random entries, chosen **

** from a normal distribution with mean 0.0 and variance 1.0. **

** RANDN(M,N) or RANDN([M,N]) is an M-by-N matrix with random entries. **

** RANDN( SIZE (A)) is the same size as A. **

** RANDN with no arguments is a scalar whose value changes each time **

** it is referenced. **

** **

** **

** RANDN('seed') returns the current seed of the normal generator. **

** RANDN('seed',s) sets the normal generator seed to s. **

** RANDN('seed',0) resets the seed its startup value. **

** RANDN('seed',sum(100*clock)) sets it to a different value each time. **

** **

** **

** RANDN and RAND have separate generators, each with its own seed. **
