how chose a number with unequal probability?

1 view (last 30 days)
My question is if I use randi function and say between 1 : 100, it chooses randomly a number giving equal probability to all numbers in between. Suppose I want to chose a number between 1 and 100 but give different probability for each number say proportional to the number itself.. so that 1 has a much lower probability to pick compared to 100 for e.g. how would I do that with randi function? Is that possible at all? Thanks in advance for any help.

Use the randsample function from Statistics and Machine Learning Toolbox with a vector of weights.
