I have this code
for i=1:5;
minValue = 0.0251;
maxValue = 3.9811 / 5; % Divide by 5 to ensure sum of 5 is less than 3.9811
randomValues = 10*(minValue + (maxValue - minValue) * rand(1,i));
end
A=randomValues;
I want to select from vector A two random value in which this values it is verify this condition
1- such one it is between 1 and 5.
for example a and b two values, the condition is
m=1;
n=5;
(a>=m && a<=n) && (b>=m && b<=n)

Your code doesn't return a vector; it just generates one value each pass thru the loop and overwrites the previous with the current...

B=A(A>=m & A<=n);%finds all numbers between m and n in A
C=B(randperm(length(B),2));%chooses 2 numbers randomly from B
