Length of a Vector (Last Nonzero Index)

Source: R/116_atoms_length.R
length_expr.Rd

Returns the index of the last nonzero element of a vector (1-based). This atom is quasiconvex but NOT convex, so it can only be used in DQCP problems (solved with qcp = TRUE).

Usage

length_expr(x)

Arguments

x

A CVXR vector expression.

Value

A Length expression (scalar).
