Can someone explain what this words (NaN and Inf) mean ? I get then as a 
result of some matrix operations, in the end I have a matrix without any 
figures just this words.

  NaN=Not a Number (e.g. 0/0=NaN)
  Inf=Machine Infinity (e.g. 1/0=NaN)
  
  In addition, x*NaN = NaN x*Inf=[+/-]Inf NaN*Inf=NaN and so on.
