I NEED TO USE MATLAB FORMAT with proper programming standards.

For a loop code, vec_a = [-29, 50, 65, 27, 38, -13, 56, 35]; new_vec = zeros(1, numel(vec_a));

allocate new_vec with zeros

for index = 1:numel(vec_a) if vec_a(index) < -30 | vec_a(index) > -17 numerator = 15*vec_a(index)^3 + 7; denominator = 19 - 8/vec_a(index); or else numerator = 8*vec_a(index)^4 - 12*vec_a(index); denominator = 12/(vec_a(index) - 9); end new_vec(index) = numerator/denominator; end Must work for any vector not just vec_a
