Hello.
How can I randomly generate just two input numbers, for example: 1 or 3; 0.95 or 1.05 ?

If you are trying to randomly generate from a set of distinct numbers, then you can use randsample() if you have the Statistics Toolbox. If you do not then see the File Exchange such as http://www.mathworks.com/matlabcentral/fileexchange/21912-sampling-from-a-discrete-distribution
In the simplest form of equal weight, to draw N times from two values stored in Samples,
Samples( 1 + (rand(1,N) > 1/2) )
but see also http://uk.mathworks.com/matlabcentral/answers/246999-probability-1-2-with-matlab-random-number-generators
