FieldList

List-like collection of ScalarField objects with batch operations.

Provides validation of unit/axis/domain consistency and convenience batch wrappers for field operations.

Key Features

• Batch Signal Processing: fft_time_all(), filter_all(), resample_all()

• Batch Selection: sel_all(), isel_all()

• Validation: Ensures all members in the list share the same axis metadata.

Example

from gwexpy.fields import ScalarField, FieldList
import numpy as np

fields = FieldList([
    ScalarField(np.random.randn(10, 4, 4, 4)),
    ScalarField(np.random.randn(10, 4, 4, 4)),
])

# Batch FFT
fft_fields = fields.fft_time_all()

# Selection on all fields
subset = fields.sel_all(axis1=slice(0, 2))
