Hi guys could you please help me in this if i could make loop like? I have attached m file too.

for k=1:N

     j=1
     E_1=1;
     while E_1>10^(-6)
        j=j+1;
        Calculate values;
        Error=abs(calculated - assumed);
        E_1=Error;
     end

     While

     end
 end

[John Petersen]

It looks "loop" like to me already. What is your problem?

Computer shows Busy .....then i have to close Matlab App forcefully....Could you please try the file i attached...

[per isakson]

replace

    while E_1>10^(-6)

by

    while E_1>10^(-6) && j<1e6

[Stephen23]

Note: don't use i or j as the loop variables, as these are the names of the inbuilt imaginary unit .

[Jan]

Remark: 10^(-6) is an expensive power operation, while 1e-6 is a constant.

Daya - look at your while loop conditions

 while E_11>Err

    % etc.

    while E_1>Err

        % etc.

    end
 end

The E_11 and E_1 are initialized but are never reset. So if we enter either of these two loops because the condition is satisfied, then we will never exit the loop because neither of these two variables change, so that is why you are getting stuck. The last (or next to last) line of both while loops should be the re-initializaton of the variable that is being used in the condition. Try doing that and see what happens!

Yes. you are right. It works. Thank you...
