MATLAB: How to generate random integers from the uniform distribution between two numbers

Question

Assume matrix A as follows:

A = [
810  840
840  870
870  900
900  930
930  960
];

For every row in matrix A,I want to generate random integers from the uniform distribution between column 1 and column 2. Also, these random numbers should be divided by 5 with decimal 0 (e.g. 810 (not 811)).

The output matrix size should be 5*1.

I think the right function is randi, but I don't know how to form it.

Answer 1

Under the assumption that you want to include the endpoints, and that the elements of A are evenly divisible by 5:

A = [
810  840
840  870
870  900
900  930
930  960
];
nrows = size(A,1);
r = zeros(nrows,1);
for nr = 1:nrows
    r(nr) = 5*randi(A(nr,:)/5);
end
