it is a good problem,but I cann't solve it
Only one verification test!? and this test already has the vector sorted.
li look up the options of the sort command
Needs (much) more tests in the Test Suite!! It would also be a good idea to include a randomly generated vector in the tests; for this random input, testing of the correct function output should be hard-coded as: assert(y(1)>=y(2)); assert(y(2)>=y(3)); ... ; assert(y(end-1)>=y(end)); [It's not the most efficient check, but anything else will risk giving away clues on possible solution codes.]
i comment for the challenge
comment = badge
I do not understand what is wrong with the solution?
I solved question with my algorithm
x=input(' give me input to obtain descending order of input')
y = zeros(size(x));
Very nice problem (:
good review of skills

Every time again, it's pretty amazing, to see what powerfull little functions are implemented in Matlab!
You can do this with one function call. See the mode flag in sort().
Remove the polynomials that have positive real elements of their roots.
Right and wrong
Find the sum of the elements in the "second" diagonal
sum of non-primes
Reverse the vector
