- n is the maximum integer random value generated;
- k is number of random values that you want generate;
- w is weigth vector that contains n weights.

Hi, I want to print random numbers from 1 to 100, but i want to specifiy that most of the numbers should be around 20. In other words, it is most likely to get 20, but other numbers can also occur. Is this possible?

Hi,
you can use randsample matlab function. (Reference: https://www.mathworks.com/help/stats/randsample.html).
y = randsample(n,k,true,w);
where:
In your case n = 100 and you must define w vector with 100 weights (value 20 will be more weighted) such that weight sum is 1.
Hope this helps.

e.g.
x = 1:100;
w = exp( -( x - 20 ).^2 / 1000 );
w = w / sum( w );

Adam's example is a good one to follow in order to create in a easy and fast way weight vector.
