Detailed Description

Multi-dimensional array container for field data.

This file defines the Array template class, a multi-dimensional array container used throughout OpenPFC for storing field data. The Array class provides:

• Efficient storage using std::vector
• Multi-dimensional indexing via MultiIndex
• Construction from FFT inbox/outbox
• Element-wise operations and transformations
• Integration with decomposed domains

Usage:

// Create 3D array matching FFT outbox
pfc::Array<double, 3> field(fft, pfc::ArrayType::Outbox);
 
// Access elements
field[{i, j, k}] = value;
