Undefined operator '/' for input arguments of type 'matlab.ui​.control.U​IControl'.

Hello, Please i have this error whene i run my interface matlab:

Undefined operator '/' for input arguments of type 'matlab.ui.control.UIControl'.

You have

    target_SINR =handles.edit5;

so target_SINR is a handle, not the content stored at the handle.

You have

            SINR2=target_SINR/currentSINR;

so you are trying to divide the handle by something.

We cannot tell what the something is:

currentSINR = findRangeSINR(handles);

does not tell us what findRangeSINR does, and the code for that function was not included.

If you want the number the user has entered in the edit5 handle then you need

target_SINR = str2double(handles.edit5.String);

Caution: this will not update as the user enters new values: it will only update when the line is re-executed.

Note that you have three loops with the general form

      for i=1:N1
          currentSINR = findRangeSINR(handles);
          SINR1=currentSINR;
      end

Unless findRangeSINR is keeping a counter or choosing information randomly, then the output of that loop is not affected by how many times you run the loop body, since you do not use i anywhere in the loop, and you completely overwrite all of SINR1 each iteration of the loop. It is not obvious why you do not just do the assignments once without a for loop.

Thanks a lot. in this code, i have a number of fetocell and femtousers.The function findRangeSINR is to calculate the SINR of each femto.I divide the total number of femtousers into 3 types N1, N2 and N3 and i want to calculate the SINR of each type of user. After, based on the calculated SINRs, I have calculated the transmission power of femto and based on SINR1, SINR2 and SINR3. That's the purpose of my code, can you help me please.

[Walter Roberson]

You would need something resembling

for i=1:N1
  currentSINR = findRangeSINR(handles, 'N1', i);
  SINR1(i) = currentSINR;
end

if each of the N1 entries had an associated value referenced (somehow) in handles.

But I have no information about what values findRangeSINR needs to work with.

Thanks.

I update the code. I have this error:

Attempted to access SINRp1(0); index must be a positive integer or logical.

You have for j=1:N1 so j starts at 1. You have SINRp1(j)> SINRp1(j-1) so on the first round that compares SINRp1(1)>SINRp1(1-1) which is SINRp1(1)>SINRp1(0) . But 0 is an index before the beginning of the array.

Thanks. I modifie my code, No errors but i still have a problem. When i simulate i have SINR: -lnf dB( false value). how can i solve this problem.

If your findRangeSINR needs to look at the handles each time and you are sending it new data by setting the UserData field, then why not just pass it the data directly instead of going through the handles structure?
