Operators

Operators build PDE terms such as gradients, divergences, Laplacians, and integrals.

Families

• Differential: \(\nabla u\), \(\nabla\cdot v\), \(\Delta u\), surface and fractional operators.
• Integral: \(\int_\Omega u\,d\Omega\), means, quadrature helpers, and convolution.
• Functional: norms, inner products, and averages.
• Linear algebra: determinants, traces, norms, and einsum-style contractions.
• Delay: delay operators for time-dependent fields.
