CircularShift: Circular Shifting of a matrix/image

In rwavelet: Wavelet Analysis

Description

Pixels that get shifted off one side of the image are put back on the other side.

Usage

CircularShift(matrix, colshift = 0, rowshift = 0)

Arguments

matrix	2-d signal (matrix).
colshift	column shift index (integer).
rowshift	row shift index (integer).

Value

result 2-d shifted signal.

Examples

A <- matrix(1:4, ncol=2, byrow=TRUE)
CircularShift(A, 0, -1)

Example output

     [,1] [,2]
[1,]    3    4
[2,]    1    2
