Sounds like a school assignment. Folks here will generally be happy to help if you show what you tried so far, and ask specific questions where you are stuck.

I tried this but this didnt work :

-while altitude < 10000

-disp(altitude(1,1))

-end

hint:

idx = 1;
while idx.^3 + 5*idx.^2 - 19 < 10000
    idx = idx + 1;
end
disp(idx)

Not clear what you mean by the initial value but if you mean the first value in the list that is 10000 less than its first value then you could use:

index = find(a <= a(1) - 10000, 1);

Above, a is your vector of numbers, e.g.,

a = [1:3 -10000:0];

this is my initial values given and i have to find when the values deceased by 10000

i tried : while altitude < 10000

disp(altitude(1,1))

end

but it didnt work out
