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.

it's double right now i.e. my data in the table in my GUI. How do i change it?
All my data is double and I want to keep that but convert double values in my table to normal array.
This is what its telling me "Undefined function 'times' for input arguments of type 'cell"
I was just getting the data i.e. x=get(handles.S,'Data') and putting into equation however it doesnt let me do that.

There is nothing to do. x is double already, so there is no need to call X = table2array(x) at all . x is already an array so you're done .

are you sure? Because when i use fsolve to solve my equation it doesn't execute it. This might be stupid but there different
From GUI table
Y =
[1.1812] ''
[1.1863] ''
[1.1968] ''
[1.2026] ''
[1.2204] ''
Normal column matrix
Y =
1.1812
1.1863

Read my answer again and then show us what whos says. You didn't run whos on x and tell us what it said like I requested. Then, do the same thing for Y if you've uncommented it.

Your right sorry about that. I guess it is some other mistake I'm making? It's so strange though. I use the push button called plot to get the data. Maybe i have to initialize/call back the table data elsewhere I'm assuming.Thanks though!

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.
