Detailed Description

Matrix to LaTeX table conversion utilities.

This file provides utilities for generating LaTeX tabular representations of matrices. It is particularly useful for visualizing adjacency matrices, distance matrices from Floyd-Warshall, and path matrices.

Features

• Customizable row and column index formatting
• Customizable cell content formatting
• Support for prefix and suffix LaTeX content
• Works with any matrix-like container

Usage Example

#include <mat_latex.H>
#include <fstream>
 
// Formatter for row indices
struct RowFormatter {
  std::string operator()(const MyMatrix& m, long i) const {
    return std::to_string(i);
  }
};
 
// Formatter for column indices
struct ColFormatter {
  std::string operator()(const MyMatrix& m, long j) const {
    return std::to_string(j);
  }
};
 
// Formatter for matrix entries
struct EntryFormatter {
  std::string operator()(const MyMatrix& m, long i, long j) const {
    return std::to_string(m(i, j));
  }
};
 
std::ofstream out("matrix.tex");
mat_to_latex<MyMatrix, RowFormatter, ColFormatter, EntryFormatter>(
    matrix, n, m, out, "\\begin{center}\n", "\\end{center}\n");

Generated LaTeX Format

The function generates a tabular environment with:

• Column headers from the column formatter
• Row headers from the row formatter
• Cell contents from the entry formatter
• Horizontal lines at top and bottom
