FieldDict

Dict-like collection of ScalarField objects with batch operations.

Validates unit/axis/domain consistency and exposes batch methods on stored ScalarField values.

Key Features

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

• Batch Selection: sel_all(), isel_all()

• Arithmetic: Supports scalar multiplication, addition, and subtraction (e.g., fields * 2)

• Validation: Ensures all fields in the collection share the same axis metadata.

Example

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

fields = FieldDict({
    "Ex": ScalarField(np.random.randn(10, 4, 4, 4)),
    "Ey": ScalarField(np.random.randn(10, 4, 4, 4)),
})

# Batch FFT
fft_fields = fields.fft_time_all()

# Scalar arithmetic
scaled_fields = fields * 2.5
