how to make looping for random data and discrete

size = [0.35,0.45,0.8] L =rand(20,6) L = ['location',size] max = 33 min = 2

For column 1,3,5 will be detect for location and each row will be use this equation which is floor(L)*(max-min)+min.

for column 2,4,6 will be detect for size and each row will be measured as below:

if random value <0.3333 will be select size no 1 which is 0.35. if 0.3334< random value <0.6666 will be select size no 2 which is 0.45 if random value > 0.6667 will be select size no 3 which is 0.8

i already do this programming but my programming to long. so i dont know to to use looping programing or find programming to integrate with this data.

i hope you guys can help me.

(You should not use the name 'size' for one of your variables, since that is the name of one of matlab's functions, so I have taken the liberty of changing it to 'sz'.)

I am having to guess about the following because I am not sure I entirely understand your description. However, if it is incorrect, perhaps you can use its ideas to develop a correct algorithm. One of my uncertainties is where you want the results to be placed. I assumed here you wanted them placed back in 'L'.

   sz = [0.35,0.45,0.8];
   max = 33;  min = 2;
   L = rand(20,6);
   L(:,[1,3,5]) = floor(L(:,[1,3,5]))*(max-min)+min;
   t1 = L(:,[2,4,6]) > 1/3;
   t2 = L(:,[2,4,6]) > 2/3;
   L(:,[2,4,6]) = (~t1)*sz(1)+(t1&(~t2))*sz(2)+t2*sz(3);
