nested for loop for array manipulation

I want to form an array and put each value from that array in an equation and get all ppossible values fir that equation. then put into another function to get answer by trapezoidal rule and multiply each respectful value with a different set of array and add all of those values

clc;
x=1;
n=2;
s=0;
z=1;
for i=2:10;
  x(i)=x(i-1)./1.25;
  g=x./4;
  a=-(x./2);
  b=x./2;
  h=(b-a)/n;
  y=(1./sqrt(2.*pi).*g).*exp(-x(i).^2./(2.*(g.^2)));
  CLF = hypot(diff(x), diff(y));    % Calculate integrand from x,y derivatives
  CL = trapz(CLF)  % Integrate to calculate arc length
  for j=2:10;
    z(j)=z(j-1)./1.25;
     surf=CL*z(j);
  end
  s=s+CL;
end
a=disp(a)
b=disp(b)
g=disp(g)
X=disp(x)
Y=disp(y)
Z=disp(z)
S=disp(s)
Surf=disp(surf)
plot(X,Y)
%just put length in 3rd dimension

Here is my current code.

Thank you all!
