Subscript indices must either be real positive integers or logicals. Error in ==> networkadjustment at 480 min(X00) What is the problem ? each element seems to be real positive integers.

From: Matt Fig on 29 May 2010 13:55 You are the 1,345,657th person to name a variable after a built-in MATLAB function, then try to call the function.

I would guess that somewhere you have an array named 'min' and matlab is objecting to the fact that the elements of X00, used as indices into 'min', are not positive integers, which in fact they are *not*. You should never give your variables the names of matlab functions, for precisely this reason. Roger Stafford

Put this function in your current directory, then just before the line that errors in networkadjustment (line 480) call CHECKVARS. function [] = checkvars() %CHECKVARS Check the variables in current workspace for function masking. % CHECKVARS finds out if one of the variables in the current workspace is % masking another function or directory or javaclass. If any variables are % masking something on the searchpath, a warning will be issued in the % command window. If no conflicts are found, CHECKVARS returns nothing. % % % Author: Matt Fig who_out = evalin('caller','who'); % Get a list of variables in caller. for ind_var = 1:length(who_out) exist_out = exist(who_out{ind_var}); %#ok Find if other names match. switch exist_out case 2 conflict_type = ' M-File function.'; case 3 conflict_type = ' MEX function.'; case 4 conflict_type = ' mdl file.'; case 5 conflict_type = ' built-in function.'; case 6 conflict_type = ' P-File function.'; case 7 conflict_type = ' directory.'; case 8 conflict_type = ' Java class.'; otherwise exist_out = 0; end if exist_out fprintf(['''',who_out{ind_var},...
