Hilbert transform query

[Lester Anderson]

Hello,

I would like to compute the Hilbert transform along orthogonal axes
for a 2D matrix, but am not sure how one applies this in Octave.

Essentially, I want to calculate Hx and Hy, the Hilbert transform in
the X an Y directions respectively.

The matrix I have is square (as a test), with x(601) and Y(601). and
what I want to find is:

Hx = hilbert(grid - x direction)
Hy = hilbert(grid - y direction)

Any pointers would be helpful.

Lester
