What is wrong in this code??

Could you please help me to solve the problem? Loop cannot stop.

Attached you can find the file. The function is digdata and the other is code. Thank you.

Answer 1

[Jan]

In this loop:

while abs(res1)>0.01
  As   = vq.*(Us(j).^2)./(16.*(pi.^2).*msksi.*fs1(j));
  res1 = As1(i)-As; 
end

you calculate the same value in each iteration. As will never change its value. Therefore this must be an infinite loop.

Due to the missing comments, the purpose of this loop cannot be guessed. Therefore a reliable suggestion of improvement cannot be given.

Sorry, I am kind of new in Matlab. I am trying to apply attached step. Equation is the As formula that I wrote.

Answer 2

I changed this code with attached code, but I think the problem is in digdata function. I would like to find vq values which correspond (As(i), Vs). There is a dimensional problem that I couldn't solve.

Please post details belonging to the question by editing the question, not as answers. Thanks.

"There is a dimensional problem that I couldn't solve." Then please post any details. Do you get an error message? Then post it completely.

The clear all in your code destroys the current work, if somebody tries to your code to help you. It is much smarter to store the code in a function instead of clearing everything brutally.

Your code will be much easier to read, if you select it an press Ctrl-I in the editor.

Thank you, I will be more careful then. I solved the problem.
