Detailed Description

Pretty-print 3D arrays to console.

This header provides the show() template function for pretty-printing 3D arrays stored in std::vector with size and offset information.

The function displays:

• Array dimensions and type
• Slice-by-slice output ([:, :, k] format)
• Formatted values with fixed precision
• Optional offset information for distributed arrays

This is particularly useful for debugging field data and visualization of small computational domains.

#include <openpfc/utils/show.hpp>
 
std::vector<double> data(4*4*4, 1.0);
pfc::utils::show(data, {4, 4, 4}, {0, 0, 0});
// Prints formatted 3D array slices
