This is an implementation of multi-variable polynomial in C++.
This library treats multi-variable polynomial as a map from indexes to coefficients.
For example, x^2 * y^2 - 2 * x * y ^2 + 3 is
{
{{2, 2}, 1},
{{1, 2}, -2},
{{0, 0}, 3}
}
First, you clone this repository.
git clone https://github.com/sukeya/multivariable_polynomial.git
Next, add the following codes in your CMakeLists.txt.
add_subdirectory(multivariable_polynomial)
Finally, add linked libraries.
target_link_libraries(your_exe PRIVATE multivar_polynomial)
Then, you will be able to use this library.
The namespace is multivar_polynomial.
The examples exist in "test" directory.
A class MultiVarPolynomial implements multi-variable polynomials.
Its interface is the same as Boost's flat_map except that it lacks merge member function.
So, please see the document of Boost's flat_map.
A class ExactOf calculates f of x as less multiplication as possible, but uses more memories.
A class PolynomialProduct implements a product of polynomials which have different variable each other (example: (1 + x + x^2) * (y + 6 * y^3 + y^10) * (1 + z)).
Its interface is the same as std::array.
So, please see the document of std::array.
A class Polynomial implements one-variable polynomials.
Its interface is also the same as Boost's flat_map except that it lacks merge member function.
So, please see the document of Boost's flat_map.
