MATLAB: Completing elements of a matrix

for loopmatrix

I have a matrix a
from a I have generated a new matrix b which have 2 new elements for 1 element of a
a = [2;3]
[m,n]=size(a)
for i=1:m
    b=[1.5*(a(i)) 2*(a(i))]
end
I want to generate a new matrix 'c' such that it includes all the sets
expected results as
c = [2 3;2 4;3 4.5;3 6]

Well I got what i was trying to do :)
Thanks @Jan for your time and help
L=4
X_Range=[L*1000/16 L*1000/10];
Shut=  [152.4; 228.6; 304.8; 381.0; 457.2; 533.4; 609.6; 685.8; 762.0; 838.2; 914.4; 990.6; 1066.8];
X = Shut(Shut>=X_Range(1,1) & Shut<= X_Range(1,2));
[m,n]=size(X);
index = 0;
for i=1:m
  Y_Range =[1.5*X(i) 2*X(i)];
  Y = Shut(Shut>=Y_Range(1,1) & Shut<= Y_Range(1,2));
  [mY,nY]=size(Y);
  for j=1:mY
    index=index+1;
    XD(index)=X(i);
    YD(index)=Y(j);
  end
end
D= [reshape(XD,[],1) [reshape(YD,[],1)]]
