I have multiple arrays filled with 10 random numbers between certain values. Now I'm trying to get the equations below (t_tank1, t_tank2, t_operation) to loop through the random number arrays, to take the first value out of every array, secondly the second value out of every array etc, to finally create a 10x1 array of t_operation. However, i keep ending up with a 10x10 matrix. I tried using a For loop, but can't seem to get it to work. Any help here?
