Least Squares

Least Squares is a numerical method implementation for polynomial approximation. This library provides a convenient way to perform polynomial approximation using the least squares method.

Features

• Read data from a file
• Perform least squares approximation for a given degree polynomial
• Print the polynomial coefficients

Installation

To use the Least Squares library, follow these steps:

1. Clone the repository:

   git clone https://github.com/username/least-squares.git

2. Build the project:

   cd least-squares
   make

Usage

To use the Least Squares library in your C++ project, follow these steps:

1. Create an instance of the LeastSquares class, providing the name of the data file:

   #include "LeastSquares.hpp"
   
   int main() {
       least_squares::LeastSquares ls("data.txt");
   
       // Perform least squares approximation for a polynomial of degree 3
       ls.least_squares_implementation(3);
   
       // Print the polynomial coefficients
       ls.printf_polynomial();
   
       return 0;
   }

2. Compile and run the program:

   g++ main.cpp -o app
   ./app
