quad_form

When <code>x</code> is constant, returns <code>t(Conj(x)) %*% P %*% x</code>
(affine in <code>P</code>).
When <code>P</code> is constant, returns a <code>QuadForm</code> atom (quadratic in <code>x</code>).
At least one of <code>x</code> or <code>P</code> must be constant.

An object-oriented modeling language for disciplined
convex programming (DCP) as described in Fu, Narasimhan, and Boyd
(2020, <doi:10.18637/jss.v094.i14>). It allows the user to
formulate convex optimization problems in a natural way following
mathematical convention and DCP rules. The system analyzes the
problem, verifies its convexity, converts it into a canonical
form, and hands it off to an appropriate solver to obtain the
solution. This version uses the S7 object system for improved
performance and maintainability.
