%the program%
a = csvread('matrix.csv');
b = csvread('vector.csv');
disp(a);
disp(b);
n = length(b)
x = zeros(n,1)
aug = [a b]
for j = 1 : n-1
for i = j+1 : n
m = aug(i,j)/aug(j,j);
aug(i,:) = aug(i,:)-m*aug(j,:);
end
end
aug
x(n) = aug(n,n+1)/aug(n,n);
for k = n-1: -1 : 1
x(k) = aug(k,n+1)-aug(k,k+1:n)*x(k+1:n) / aug(k,k);
end

%the error i get%
The optional second input to exist must be 'var', 'builtin', 'class', 'dir' or 'file'.
