barak.interp.trilinear_interp(x, y, z, xref, yref, zref, vals)[source]¶

Trilinear interpolation.

Parameters :	x, y, z : arrays of floats, shapes (M,), (N,), (O,) Coordinate grid at which to interpolate vals. xref, yref, zref : array of floats, shapes (I,), (J,), (K,) Reference coordinate grid. The grid must be equally spaced along each direction, but the spacing can be different between directions. vals : array of floats, shape (I, J, K) Reference values at the reference grid positions.
Returns :	output : array of floats, shape (M, N, O)
