expr_sign

Returns the sign of an expression under DCP analysis. Use this instead
of <code><a href="/link/sign()?package=CVXR&version=1.9.1" data-mini-rdoc="CVXR::sign()">sign()</a></code>, which conflicts with the base R function.

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.
