power: Create a Power atom

In CVXR: Disciplined Convex Optimization

Create a Power atom

Description

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.
