MATLAB: How to generate and precise double value

MATLABprobability

Hello

I want to ask you How I can generate probability values randomly between 0 and 1, but 1 and 0 can include as probability value

for example

I have a vector of values X=[12 5 10 50 22]

each value of X must have a probability where 0<=p>=1

when I obtain probability like 0.98555 I want just pick 0.9

How I can do that.?

Please help me!

randi([0 10], size(x))./10

Since your t matrix is full of 0 and 1 you can take advantage of that and just do this

a = [0.9 0.8 0.7 0.6 0.5];
b = [0.1 0.2 0.3 0.4 0.5];
t = ff2n(n);
t1 = t.*a
t1 =
         0         0         0         0         0
