An array where the k-term corresponds to the (k+1)-st lowest value of the expected return of teh Portfolios on the Efficient Frontier at the values at which it is known.
assetWeights
An array of dimensional two, where the k-th element is a array which contains the weights of the assets of the Portfolio on the Efficient Frontier with the (k+1)-th lowest values of the expected returns.
Remarks
This allows a portfolio
(i.e. point) on the Efficient Frontier which has previously be evaluated to be used within
the present analysis. This means for example that a pre-evaluate portfolio on the Efficient
Frontier can be persisted by storing the associated expected return and asset weights within
a database.
