I have a large code and I'm stuck on using cell arrays. I have some x values in cell array and i want to assign them with a function. There is a loop, function is working correct in first loop with first x cell array. But there is some error after second iteration, function didn't return true values.
x =
[-4.6250] [-3.5750]
[-3.8750] [-2.2250]
[-3.1250] [-0.8750]
[-2.3750] [ 0.4750]
[-1.6250] [ 1.8250]
[-0.8750] [ 3.1750]
[-0.1250] [ 4.5250]
[ 0.6250] [ 5.8750]
[ 1.3750] [ 7.2250]
[ 2.1250] [ 8.5750]
[ 2.8750] []
[ 3.6250] []
[ 4.3750] []
[ 5.1250] []
[ 5.8750] []
[ 6.6250] []
[ 7.3750] []
[ 8.1250] []
[ 8.8750] []
[ 9.6250] []
My function is
f = cellfun(@(x) x.^2-3.*x+5,x);
I didn't initialize it as array or anything. Error is
Error using cellfun
Non-scalar in Uniform output, at index 31, output 1.
Set 'UniformOutput' to false.
Error in neg (line 1)
f = cellfun(@(x) x.^2-3.*x+5,x);
After I did 'UniformOutput' to false as it said, but then the function didn't return minus values. I want function to work for all x values. I have missing information about cell array. Can you give me any suggestion?

I do not see the problem.
C = {[-4.6250] [-3.5750]; ...
[-3.8750] [-2.2250]; ...
[-3.1250] [-0.8750]; ...
[-2.3750] [ 0.4750]; ...
[-1.6250] [ 1.8250]; ...
[-0.8750] [ 3.1750]; ...
[-0.1250] [ 4.5250]; ...
[ 0.6250] [ 5.8750]; ...
[ 1.3750] [ 7.2250]; ...
[ 2.1250] [ 8.5750]; ...
[ 2.8750] []; ...
[ 3.6250] []; ...
[ 4.3750] []; ...
[ 5.1250] []; ...
[ 5.8750] []; ...
[ 6.6250] []; ...
[ 7.3750] []; ...
[ 8.1250] []; ...
[ 8.8750] []; ...
[ 9.6250] []};
F = cellfun(@(x) x.^2-3.*x+5, C, 'Uni', false);
This works as expected and the result is correct, even for the negative values:
x = -3.5750;
disp(x.^2-3.*x+5)
disp(F{1, 2})
