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) )

Thank you so much) You helped me out again
