how can i format output2 in the following code by using for loop

f=@(x) x.^2;
x= [0.1 0.3 0.5 0.6 0.66 0.9 1];
for i =1:length(x)
   output1{i}= f(x(i))';
end 
output2=[ f(x(1))'  f(x(2))' f(x(3))' f(x(4))' f(x(5))' f(x(6))' f(x(7))'];
%---------------------------------
output1{1:length(x)}
output2

result:

ans =
    0.0100
ans =
    0.0900
ans =
    0.2500
ans =
    0.3600
ans =
    0.4356
ans =
    0.8100
ans =
     1
output2 =
    0.0100    0.0900    0.2500    0.3600    0.4356    0.8100    1.0000

Note:

1.The differnent between output1 & output2, formatting

2. The previous code is brief for 7 digit (size(7,1), so easy to write manually. So, i want using for loop for large size(n,m).

is there a particular reason why you are using cell array to record the output of f(x)?

在 MATLAB Online 中打开

f=@(x) x.^2;
x= [0.1 0.3 0.5 0.6 0.66 0.9 1]
x = 1×7
    0.1000    0.3000    0.5000    0.6000    0.6600    0.9000    1.0000
output1 = arrayfun(f, x)
output1 = 1×7
    0.0100    0.0900    0.2500    0.3600    0.4356    0.8100    1.0000
