We need to modify Amat and bvec to include the constraint of no shorting. In producing, we wish to include a diagonal matrix of kinds to Amat as well as a vector of zeros to bvec, which operates out when undertaking the matrix multiplication that for every weight, its benefit should be better than zero.
That is a strong addition to Markdown, as it permits customized visuals, tables and in some cases interactive visualisations, to be A part of your R files.
