i need to store the each iteration values in consecutive rows.how it is possible in matlab?

   for i =1:3
    a=rand(3,2);
    b = reshape(a.',1,[]);
end
ex:
 i=1; b= 0.1174    0.4242    0.2967    0.5079    0.3188    0.0855
 i=2: b= 0.1174    0.4242    0.2967    0.5079    0.3188    0.0855
 i=3;  b= 0.9133    0.2619    0.7962    0.3354    0.0987    0.6797
output should be a variable(3*6)
   0.1174    0.4242    0.2967    0.5079    0.3188    0.0855
   0.1174    0.4242    0.2967    0.5079    0.3188    0.0855
   0.9133    0.2619    0.7962    0.3354    0.0987    0.6797

在 MATLAB Online 中打开

 b = zeros(3,2*3);
 for k = 1:3
   a = rand(3,2);
   b(k,:) = reshape(a.',1,[]);
 end

Note: Your output is 3 by 6, not 3 by 5.

在 MATLAB Online 中打开

your_output = zeros(3,6); % initialization of variable
for i =1:3
    a=rand(3,2);
    b = reshape(a.',1,[]);
    your_output(i,:) = b;
end
your_output =
    0.6787    0.3922    0.7577    0.6555    0.7431    0.1712
    0.7060    0.0462    0.0318    0.0971    0.2769    0.8235
    0.6948    0.0344    0.3171    0.4387    0.9502    0.3816
