how should i put the data in gui uitable

5 views (last 30 days)
hey, i am beginer in GUI and i have written this code in gui which i used 2 uitable and in first one the user should enter all data for columns number 1 and 3 and just first cell of columns 2, 10 and 11 and put sum of spitial culomns in uitable 2. but i have evaluating eror in this push buttom. thank for help.
data = get(handles.ut1,'Data');
A = data(:,1);
[m n]=size(A);
G = zeros(m,n);
G(1) = data (1,2);
for i=2:m
G(i)=G(i-1)+A(i-1)-180;
if G(i)>360
G(i)=G(i)-360;
elseif G(i)<0
G(i)=G(i)+360;
end
end
d = data(:,3);
deltax = zeros(m,n) ;
deltay = zeros(m,n) ;
cx=zeros(m,n) ;
cy=zeros(m,n) ;
deltaxc = zeros(m,n) ;
deltayc = zeros(m,n) ;
for i = 1:m ;
G(i)=G(i)*(pi/180);
deltax(i)=d(i)*sin(G(i));
deltay(i)=d(i)*cos(G(i));
cx(i)=(-d(i))*(sum(deltax)/sum(d));
cy(i)=(-d(i))*(sum(deltay)/sum(d));
deltaxc(i)=deltax(i)+cx(i);
deltayc(i)=deltay(i)+cy(i);
end
x=zeros(m,n);
y=zeros(m,n);
x(1) = data (1,10);
y(1) = data (1,11);
for i=2:m;
x(i)= x(i-1)+deltaxc(i-1);
y(i)= y(i-1)+deltayc(i-1);
end
res = [A, G ,d, deltax, deltay, cx ,cy, deltaxc, deltayc ,x, y];
set(handles.ut1,'Data',res)

One thing that you need to keep in mind is that the Data property for a uitable is normally a cell array, so that a uitable may have data in multiple formats. However it is also allowed for the Data property to be a numeric array. Your code has been written under the assumption that you will always be dealing with a numeric array. That is not exactly wrong but it is a bit fragile. You would be safer checking whether you had a cell array with iscell() and using cell2mat() if it is a cell.

thanks. I get what you said but I don't know where exactly I should check it(iscell) and will the gui run after solving this? I use cell2mat for data and I again have same errors.

data = get(handles.ut1,'Data');
if iscell(data); data = cell2mat(data); end
If you look further in your code you can see that you have one callback that does
data(end+1,:)={0};
indicating that in that routine you are expecting the uitable to be a cell array. You need to be consistent in how you handle the array. Your lines
res = [A, G ,d, deltax, deltay, cx ,cy, deltaxc, deltayc ,x, y];
set(handles.ut1,'Data',res)
are going to send a numeric array to the uitable even if it started as a numeric table, and if it is a numeric table then appending the {0} to it is going to fail.
You should review all of your code and switch it all to expecting cell array. For example,
set(handles.ut1,'Data', num2cell(res))
