Hi, please how i can solve this problem:

Maximum recursion limit of 500 reached. Use set(0,'RecursionLimit',N) to change the limit. Be aware that exceeding your
available stack space can crash MATLAB and/or your computer.

My code:

function [Pmacro Pfemto] = UAQP_power_control_method(handles)

Hi, the fuction is findRangeSINR and this is the code of this function:

function currentSINR = findRangeSINR(handles)
R = str2num(get(handles.edit11,'String'));
coordVectors = get(handles.figure1, 'UserData');
numOfFemtocells = min(size(coordVectors.femt_x, 2), size(coordVectors.femt_y, 2));
currentSINR=zeros(1,numOfFemtocells);
for i=1:numOfFemtocells
    x1 = coordVectors.femt_x(i);
    y1 = coordVectors.femt_y(i);
      x = [x1 x1 max(x1-R,0) min(x1+R,496)];
      y = [min(y1+R,428) max(y1-R,0) y1 y1];
      [SINR, G, PL, numOfWalls, dist, isIndoor] = SINRfemto(x, y, i, handles);
      if histc(coordVectors.att_cell, i)==0
          NoF=1;
      else
          NoF = histc(coordVectors.att_cell, i);
      end
      currentSINR(i) = min(SINR)/NoF;
  end

@brahmi ibtissem: I still don't see anything obvious that would cause recursion of those functions. You should check if the filenames match the function names: this can cause recursion, and users can easily miss this. Double check the filenames against the function names!

If you still cannot find anything please upload your files in a new comment.
