convolve: 1D discrete convolution (numpy-style)

In CVXR: Disciplined Convex Optimization

1D discrete convolution (numpy-style)

Description

convolve() is CVXPY 1.9's preferred name for conv (CVXPY's conv class is deprecated in favor of convolve). For a CVXR Expression argument it builds a Convolve atom, the numpy-style convolution (numpy.convolve(x, y) == stats::convolve(x, rev(y), type = "open")). If neither argument is an Expression the call is forwarded as written to convolve, so the result is exactly stats' (circular by default).

Usage

convolve(x, y, conj = TRUE, type = c("circular", "open", "filter"))

Arguments

x, y	Expressions or numeric vectors; at least one must be constant when building an atom.
conj, type	As in convolve; only for plain numeric input, an error with an Expression.

Value

A Convolve atom (for expressions) or a numeric vector.
