How can I fix value of vector inside for loop ?

how can I fixed the value of " select_angles " in case the condition is satisfied ? I tried to fix it via using repeat element function but didn't work.

I appreciate any help.

angles = [ 20 45 60 30 90];
randomize_angles=randperm(numel(angles));
for i=1:numel(randomize_angles)
    select_angle = angles(randomize_angles(i))
    if condition 
        select_angle = repelem(pickangle11,1)
    end
end

condition = something

Not clear what you mean.

@Torsten thanks for your query, actually I mean how can I fix the value of "select angles which is changing in each iteration of the for loop " due to I have condition when that condition is satisfied I want to stop this select angle and prevent it from choosing another angle, that's why I tried to use the repeat element to try repeat the same angle in away let the vector select angle repeat the same value. I hope I let you get my point.

Your assignment is not quite clear but to the best understandinbg of mine. Note that repelem(A,1) if A is a scalar, the result is A. This is how your assignment can be solved, e.g.:

angles = [20 45 60 30 90];
randomize_angles=randperm(numel(angles))

randomize_angles = 1×5

1 3 2 4 5

for i=1:numel(randomize_angles)
    select_angle = angles(randomize_angles(i))
    if select_angle==angles(i) 
        select_angle = angles(i)
    end
end

select_angle = 20

select_angle = 20

select_angle = 60

select_angle = 45

select_angle = 30

select_angle = 30

select_angle = 90

select_angle = 90

thanks for your replay. yes I think my question wasn't clear, but I wanted to to fix the angle when the condition is satisfied but still the loop test another angles

Most welcome! Good luck with your exercise.

[Voss]

angles = [ 20 45 60 30 90];
randomize_angles=randperm(numel(angles));
selection_made = false;
for i=1:numel(randomize_angles)
    if ~selection_made
        select_angle = angles(randomize_angles(i))
    end
    if condition 
        selection_made = true;
    end
end

Thank you for your answer, I tried this way but doesn't work due to when the condition is satisfied the for loop continues in iteration another angle not fix the angle that condition satisfied at.

[Voss]

After the condition is satisfied, yes, the for loop continues to iterate, but, no, another angle is not assigned to select_angle.

If you want to stop the for loop as soon as the condition is satisfied, use break:

angles = [ 20 45 60 30 90];
randomize_angles=randperm(numel(angles));
for i=1:numel(randomize_angles)
    select_angle = angles(randomize_angles(i))
    if condition 
        break
    end
end
% now select_angle is your angle, use it from here on
