I am trying to use below code to calculate and write into new variable but it's taking last value and giving same whole vector.

for k=1:3
    for j = 22:24 
        %three values expected and write into A
      A(k,:) = (f1_lh_nwaer(j,25)+f1_lh_nwaer(j+1,25))/2; 
    end
end

output:

A = [0.5;0.5;0.5]

在 MATLAB Online 中打开

if i understood correctly then,

it is because your inner loop runs over j several times for each k value

hence in A the k position which you have given is overwritter for each j.

count = 1;
for k=1:3
    for j = 22:24 
        %three values expected and write into A
      A(count,:) = (f1_lh_nwaer(j,25)+f1_lh_nwaer(j+1,25))/2; 
      count = count+1;
    end
end

if this doesnt solves your query then please do explain your problem in other way as is it difficult to understand your current description of problem
