# Data formatΒΆ

tidynamics assumes that the data is provided as NumPy arrays where the first dimension is the time and the second dimension, if it exists, consists in the spatial coordinates of a the trajectory.

Data is assumed to be sampled at equal time intervals.

For a 2D position dataset `pos`

, \(x(t)\) is stored in `pos[:,0]`

and \(y(t)\)
is stored in `pos[:,1]`

.
