2. a)Write a well-commented Matlab function program that calculates the sum of the squares of the first n integers. b)Write a well-commented Matlab function program to do Newton’s method for a function f until |f(x)| < tol. Let f, f 0 , x0 and tol be the inputs and the final x be the output.

Solution

n=5;
function sumall = sqare_sum(n)
sumall = 0;
for j = 1:n
sumall = sumall+j^2;
end
//disp(answer);

function [ x,sx ] = newtosns( f, f0, x0, tol, m )
if gn == 3
tol = 1e-4;
m = 1e1;
elseif gn == 4
m = 1e1;
elseif gn ~= 5
error(\'invalid\');
end
  
f = inline(f);
f0 = inline(f0);
x(1) = x0 - (f(x0)/f0(x0));
ex(1) = abs(x(1)-x0);
s = 2;
while (sx(s-1) >= tol) && (s <= m)
x(s) = x(s-1) - (f(x(s-1))/f0(x(s-1)));
sx(s) = abs(x(s)-x(s-1));
s = s+1;
  
end
