Quick Start

You can start building an app using imeth by including a category and its chapter in your code like this:

#include <imeth/linear/algebra.hpp>

Then start using the methods imported from the header like this:

int main() {
    // Solve: 2x + 4 = 0
    // Solution: x = -2
    auto solution = imeth::LinearAlgebra::solve_1v(2, 4);

    if (solution) {
        std::cout << "Solution: x = " << *solution << "\n";
    } else {
        std::cout << "No solution exists\n";
    }

    return 0;
}

Example: Solving a System of Linear Equations

Let's make a program to solve linear equation of two variables using imeth:

#include <imeth/linear/algebra.hpp>
#include <iostream>

int main() {
    // Solve:
    //   2x + 3y = 8
    //   4x - 2y = 0
    // Solution: x = 1, y = 2

    auto solution = imeth::LinearAlgebra::solve_2v(2, 3, 8,    // First equation coefficients
                                                   4, -2, 0);  // Second equation coefficients

    if (solution) {
        std::cout << "Solution: x = " << solution->first
                  << ", y = " << solution->second << "\n";
    } else {
        std::cout << "No unique solution exists\n";
    }

    return 0;
}

Here, I call the library imeth, then the category linear, and then the chapter algebra.hpp.

What I'm really doing is, I'm importing the methods from the algebra chapter (header file, algebra.hpp) from the linear category (linear/) of the imeth library (imeth/).
