exo_skryer.aux_functions.simpson_padded(y: Array, x: Array, n_valid: Array, *, axis: int = -1, even: str = 'first')[source]#

Composite Simpson integration for padded arrays with non-uniform spacing.

Parameters:

yndarray: Function values, padded to Nmax along axis.
xndarray: Sample points (same shape as y), padded to Nmax along axis. Must be strictly increasing on the valid prefix [0:n_valid].
n_validint or ndarray: Number of valid (unpadded) points along axis (>= 2). Can be scalar int or per-batch int array (vmap-friendly).
axisint, optional: Axis of integration. Default: -1
even{‘first’, ‘last’, ‘avg’}, optional: Handling when n_valid is even: - ‘first’: Simpson on first n_valid-1 + trapezoid on last interval - ‘last’: Trapezoid on first + Simpson on last n_valid-1 - ‘avg’: Average of ‘first’ and ‘last’ Default: ‘first’

Returns:
