prod_entries: Product of entries along an axis

In CVXR: Disciplined Convex Optimization

Product of entries along an axis

Description

Used in DGP (geometric programming) context. Solve with psolve(problem, gp = TRUE).

Usage

prod_entries(x, axis = NULL, keepdims = FALSE)

Arguments

x	An Expression
axis	NULL (all), 1 (row-wise), or 2 (column-wise)
keepdims	Whether to keep reduced dimensions

Value

A Prod atom

Examples

x <- Variable(3, pos = TRUE)
prob <- Problem(Minimize(prod_entries(x)), list(x >= 2))
## Not run: psolve(prob, gp = TRUE)
