Hi everyone! I can't seem to populate my uitable. I want the first column to be names and the second and third numbers so i do the following:
char1=char(names);
dat={char1 acc sp};
set(handles.uitable1,'Data', dat, 'RowName',num);
,but i get the following error:
Data within a cell array must have size [1 1]
Please help what am i doing wrong? Ive tried setting the Column format to ''char'', but still no luck. Thanks in advance!

dat={ cellstr(char1) num2cell(acc(:)) num2cell(sp(:)) };

Thanks but now I'm getting
??? Error using ==> set
Values within a cell array must be numeric, logical, or char
I tried using cellstr before and got the same message again...it really is the name column that is the problem, but i can't go without it :/

What is class(acc) and class(sp) and class(num) ?

it's one class that stores information about acceleration and speed of sport players. what i did is to get the names:
for i=1:size(all,2)
names(:,i)=all(i).Name;
num(i,1) = all(i).Number;
end
then for the table i just need the maximum values so i do this:
for i=1:size(all,2)
abs1=abs(all(i).Acceleration(:,1));
abs2=abs(all(i).Acceleration(:,2));
temp=abs1+abs2;
acc(i,1) = max(temp);
abs3=abs(all(i).Speed(:,1));
abs4=abs(all(i).Speed(:,2));
temp1=abs3+abs4;
sp(i,1)=max(temp1);
end
char1=char(names);
end the rest is the one posted above...the strange thing is that it works fine if the class has only one object(player) but when they become more it gives that error....

dat=[ cellstr(char1) num2cell(acc(:)) num2cell(sp(:)) ];
(Change of {} to [])
Why are you writing the names in as _columns_ instead of rows? You should just construct
names = {all.Name};
and then
dat=[ names(:) num2cell(acc(:)) num2cell(sp(:)) ];

Hey Thanks that worked like a charm!And to answer your question I have to shamefully admit that I'm pretty new to matlab and programing at all.
I thought i needed the columns for the uitable, but i guess I don't really:)
I tried your suggestion, but I also use this to make a legend on the plot and it says it needs to be a string so I put cellstr(names), but then got error in cellstr itself...and it's all very confusing :D
But thanks you've been great help, I think that would work even though it's a bit heavy as I now realize :)

When
names = {all.Name};
then to use those names as a legend, use
legend(names{:})

Solved the problem:
entered doubles via num2cell(double) and strings via cellstr.
[code] B(i)=cellstr(string1{i});
TE = [num2cell(double1') num2cell(double2) cellstr(B)'] [/code]
Thanks a lot!
