I want to exit from the loop when successive matrix value is too close.For example:. For n=1:100 If f(n+1)==f(n) Break; end; end; It also good if I compare upto 4 digits or some tolerance value. Is there any matlab function is there for it?

check this example;
% examle
tol=1e-4
xold=1e10
for i =1:100
xnew = ....
if abs(xnew-xold) < tol
break
end
xold=xnew;
end

In this case, it can be solved using round(D, n) to set up the tolerance value. Where n is correct decimal digits.
