We present a straightforward, algebraic method for calculating the Yukawa couplings of a large class of non-standard embedding heterotic compactifications on Calabi-Yau threefolds. Our methodology covers, although is not restricted to, the positive monads over complete intersection Calabi-Yau manifolds. The algorithm involves the manipulation of polynomials and can be straightforwardly implemented on a computer. We present explicit examples and show how models with one Higgs multiplet and a rank-one mass matrix can be engineered.
