MATLAB: How to generate probability value randomly

MATLABprobability

Hello,

I have a set of discrete value

X=[1 , 2, 10, 5, …., 4]

I want each value in X contains a probability value between 0 and 1

example:

1: 0.5,

2:0.1,

5:0.9

…..

Thanks.

Try this

X = [1 , 2, 10, 5,  4];
prob = rand(size(X))
