4.2.3. qeq

This module defines the interface for solving a quadratic equation.

The quadratic equation is of the form:

\[ a x^2 + b x + c = 0, \]
where \(a\), \(b\), and \(c\) are the coefficients of the equation.

Of course, this is not very useful in scientific context to invoke such a solver.

It was developed as a prototype to ensure that the envisioned architecture of Open Interfaces is feasible. It is used as a simple text case as well.

Functions

int oif_solve_qeq(ImplHandle implh, double a, double b, double c, OIFArrayF64 *roots)

Solve the quadratic equation \(a x^2 + b x + c = 0\).

Parameters:

  • implh – [in] Implementation handle

  • a – [in] Coefficient of the quadratic term

  • b – [in] Coefficient of the linear term

  • c – [in] Constant term

  • roots – [out] Roots of the quadratic equation
