Flip
(N, dims=None, dir=0, dtype='float64')[source]¶ Flip along an axis.
Flip a multi-dimensional array along a specified direction
dir
.Parameters: Notes
The Flip operator flips the input model (and data) along any chosen direction. For simplicity, given a one dimensional array, in forward mode this is equivalent to:
\[y[i] = x[N-i] \quad \forall i=0,1,2,...,N-1\]where \(N\) is the lenght of the input model. As this operator is self-adjoint, \(x\) and \(y\) in the equation above are simply swapped in adjoint mode.
