How do I set a while loop that runs until all elements meet the condition? For instance:
t = -100:200;
F = t;
indices = 1:100;
while F(indices) < 0 %
indices = indices + 1;
end
This while-loop only will run, until one of the elements of F(indices) will be creater than 0. However I wish it will run until all of the elements will meet the condition. How to implement this?

t = -100:200;
F = t;
indices = 1:100;
while all(F(indices)<0)
indices = indices + 1;
end

I also thought of it but apparently this is not working because it also stops as soon as one component is greater zero. If it was working right, indices should be an array from 101:201 actually.

Then you must code
t = -100:200;
F = t;
indices = 1:100;
while any(F(indices)<0)
indices = indices + 1;
end
Then the while loop continues until all elements of F(indices) are >=0.

Yes, @Torsten is correct, I did not properly understand the question before.
