MATLAB: Making new code by calling 3 different RANDOM variables

making new code by calling 3 different random variables

This function will generate a normal distribution conditional by bounds:

i have used above code 3 times and made 3 random variables c, fi, G. now i want to calculate qult.
this is my code :for getting distribution of qult i need to produce 3 different random variables (c, fi, G) by above code and call them in a new code to get answer. how should i use c, fi, G that i produced and call them in a loop to compute qult.
this is my code for qult:
B=1000;L=2000;Sc=1.1;Sq=1.1;Sgama=.8;
nsamples=10000;
   for i=1:nsamples
       C=C(1,i);
       G=G(1,i); 
       fi=fi(1,i);
Nq=tan((pi/4)+(pi*fi/360))*tan((pi/4)+(pi*fi/360))*2.718^(pi*tan(fi*pi/180));
       Nc=(Nq-1)*cot(fi*pi/180);
       Ngama=2*(Nq+1)*tan(fi*pi/180);
       qult(i)=(C*Nc*Sc)+(384*Nq*Sq)+(980*Ngama*Sgama);
   end

On the first iteration through the loop, your statements
       C=C(1,i);
       G=G(1,i); 
       fi=fi(1,i);
are equivalent to
       C=C(1,1);
       G=G(1,1);
       fi=fi(1,1);
That is, you take a single value out of the array C and you replace the entire array C with that single value; likewise for G and fi. So after the first iteration, C and G and fi each only have one element left.
What you should do is rename your C, G, and fi variables so that you are not storing over your C, G, and fi arrays.
