Polynomial library with basic funtions and operators (+,-,*)

Primary LanguageC++

Polynomial library [C++]

The library is written in C++ using class template vector and allows basic polynomial operations, such as:

  • sum between polynomials
  • difference between polynomials
  • assignment
  • multiplication between polynomials
  • multiplication by constant values

Moreover it allows basic polynomial representation (example: 1+0x+2x^2/1+1x)

Usage

Import library:

#include "polynomial.h"

Call constructor

There are three ways to call it depending on the needs:

Polynomial polyName(vector<float> numerator,vector<float> denominator);
Polynomial polyName(vector<float> numerator);
Polynomial polyName(int polySize, float value);

  • numerator is a vector of floats, the first value is the 0 order coefficient, the n value is the n-1 order coefficient;

  • denominator is a vector of float and is used the same way as the numerator;

  • polySize is an integer and represents the size of the polynomial;

  • value is the float value used to fill the polynomial coefficients.

Operations

In order to work with ease operator overloading has been used.

Assignment example

Polynomial poly2 = poly1;

Addition example

Polynomial poly3 = poly2 + poly1;

Subtraction example

Polynomial poly3 = poly2 - poly1;

Multiplication example

Polynomial poly3 = poly2 * poly1;
