Nested For loop to test two data sets

I need help running through two sets of data to send to a function. I want to run each value of d for the entire range of Q values and store it in a matrix. This is what I could think of but this only tests a single d value for a single Q value. Please help me.
i=1
for d=1:1:5
for Q=10:1:15
[Re]= Reynold(d,Q);
Reynolds(i,1)= Re;
i=i+1
end
end

Oh, I forgot the part that you wanted to feed your function with d and Q, but you can still use the matrix for this purpose. Re =Reynolds(d(i),A(i,:)) This statement will make the function to run i times, one output for each value of d and the corresponding values of Q. Note that A (i, :) is a vector value of Q for every d value.

d = 1:5;
Q = 10:15;
N = length(d);
M = length(Q);
v = zeros(1,M);
A = zeros(N,M);
for i = 1:N
for k =1:M
v(k) = Q(k);
A(i,:) = v;
end
end
disp(A)

This code would do the trick, each row of the matrix A represents the number of times that d runs and the columns are the values of Q.

N = 5 ;
D = 1:1:5 ;
Q = 10:1:!5 ;
Re = zeros(length(D),length(Q),N) ;
for i=1:N
R = zeros(length(D),length(Q)) ;
for d=1:length(D)
for q=1:length(Q)
R(D(d),Q(q)= Reynold(D(d),Q(q));
end
end
Re(:,:,i) = R ;
end
