Create a Power atom — power • CVXR

Create a Power atom

Usage

power(x, p, max_denom = 1024L, approx = TRUE)

Arguments

x: An Expression (the base), OR a positive constant if p is a variable (the identity b^x = exp(x * log(b)) is used).
p: Numeric exponent, Parameter, or Expression. If p is a non-constant Expression and x is a positive constant, dispatches to exp(p * log(x)).
max_denom: Maximum denominator for rational approximation
approx: If TRUE (default), use SOC approximation. If FALSE, use exact power cone.

Value

A Power or PowerApprox atom, or an exp expression for the const-base case.

Note

sqrt(x) on a CVXR expression dispatches to Power(x, 0.5) via the Math group generic. See math_atoms for all standard R function dispatch.
