I want to store output values of x1,g(x) etc in a matrix,plz help me out. here's my program:
function SA()
x1=input('\n enter initial value:-');
acc=input('\n enter accuracy:-');
n=input('\n itterations:-');
while (dg(x1)>1)
x1=input('\n enter initial value:-');
end
fprintf('\n n x1 x2 (x2-x1) g(x1) ');
for i=1:1:n
x2=g(x1);
fprintf('\n %d %f %f %f %f',i,x1,x2,abs(x2-x1),g(x1));
if abs(x2-x1)>acc
x1=x2;
else
fprintf('\n root is %f',x2');
break;
end
end
end
function y=g(x)
y=(((x^2)+1)/3);
end
function z=dg(x)
z=((2*x)/3);
end

Initialize another variable say X3 as X3 = []
Then use X3 to store x1 and g(x) values
Modify this portion of code as
X3 = [];
x1=input('\n enter initial value:-');
acc=input('\n enter accuracy:-');
n=input('\n itterations:-');
X3 = [X3 x1];
while (dg(x1)>1)
x1=input('\n enter initial value:-');
X3 = [X3 x1];
end
Then other changes in below portion of Code
if abs(x2-x1)>acc
x1=x2;
X3 = [X3 x1];
else
fprintf('\n root is %f',x2');
X3 = [X3 x2];
break;
end
