Hey guys would anyone know what is wrong with my code? I have two single tables set up i.e. (71 rows x 1 column) called S and R (tag names). And i want to convert them into simple column matrix i.e. arrays. However from point of %ok i get stuck. Would anyone know what is wrong? I think it is to do with 'table array' being different to 'column matrix' or fsolve not executing for some reason

             d = str2double(get(handles.dp,'string')); %ok
        o = str2double(get(handles.oi,'string'));%ok
        w = str2double(get(handles.w,'string'));%ok
       m = str2double(get(handles.m,'string'));%ok
       d=d*10^-6;%ok
       b0= [1.98; 2.15*d];%ok
       X=get(handles.S,'Data');%OK
      Y=get(handles.R,'Data');%OK
      options=optimset('Display','iter'); %OK
      myfun = @(b) [((1-w.*((((b(2).*(d).^(2-b(1)))./(o.*Y.*X)).^(1/(4-                       b(1))))./(d)).^(3-b(1)))./((1)-(w.*((((b(2).*   (d).^(2-b(1)))./(o.*Y.*X)).^(1/(4-b(1))))./(d)).^(3-b(1)))./m).^2)-Y]  %OK
opts = optimoptions('fsolve', 'TolFun', 1E-8, 'TolX', 1E-8); %OK
      [b,fval,exitflag] = fsolve(myfun,b0)  %%%??????????? i think this might be causing problem?

What is the data type of x? If your uitable is all numbers, x is probably a double array. If not, then x might be a cell array or a table. What does this say

whos x

To use table2array(), x must be of class "table" and not double or cell.

I'm still not sure what you want to do. Somehow you put x into uitable S, and Y into uitable R, and you simply want to extract them back out of those uitables. So what is the problem? You're getting x out and it's a double array. What is wrong with that?

Yes, but when i use fsolve to solve it, it gives me an error saying "Undefined function 'times' for input arguments of type 'cell'" when i did run my program without GUI it perfectly solved for it where x and y were column matrices or arrays. However fsolve doesn't seem to do solve it anymore now. I tried debugging it and this is where i get stuck.

Thanks.
