Hi,

How can i impliment a convergence condition in a loop. (the condition is A(k,i)-A(k+1,i)<=0.0001)

and with another condition :( if the condition is true continue, else replace the the last value and repeat).

for emample:

for k=1:t (time loop)

for i=1:10

A(i)=....

end

end (for k)

abdel - perhaps your condtion would be

if abs(A(k,i) - A(k+1,i)) <= 0.0001
    % do nothing
else
    % replace your value
end

Since we do nothing if the condition is true, we could simplify the above code to

if abs(A(k,i) - A(k+1,i)) > 0.0001
    % replace your value
end

i tried this, but it take a lot of time without give any result.

maybe this is the wrong condition to use then. Try stepping through the code with the debugger to understand why you might not be getting a result.
