[julia-users] Re: Can the function "circshift" be extended slightly?

[Carlos Baptista]

Or maybe just write a completely new function:

function circupdate!(A, x)
    (n, m) = size(A)
    assert n == length(x)

    for j = 2:m
        for i = 1:n
            A[i, j-1] = A[i, j]
        end
    end

    for i = 1:n
        A[i, m] = x[i]
    end
end
