### Usage

    RidgeSampling(phi, nbnodes)

### Arguments

`phi` | ridge (1D array).
`nbnodes` | number of samples.

### Details

Gabor ridges are sampled uniformly.

### Value

Returns a list containing the discrete values of the ridge.

`node` | time coordinates of the ridge samples.
`phinode` | frequency coordinates of the ridge samples.
