Detailed Description

The base class for the polynomial solvers.

The classes derived from this one, are able to isolate the unknowns from equations which can be written in this form:

a_1*x^n + a_2*x^(n-1) + a_3*x^(n-2) ..... + a_n*x^0 = 0

Public Member Functions

 mcPolySolver ()
virtual ~mcPolySolver ()
bool math_SolveLine (mcMathLine &p, const mcSymbolProperties *unk, mcSystemStepArray &)
 Prepares the given line for real solving, determines the degree of the given symbol and calls the right solver for the supported equations degrees.
bool math_SolveLineFirstDegree (mcMathLine &p, const mcSymbolProperties *unk, mcSystemStepArray &steps)
 Solves equations of the first degree.
bool math_SolveLineSecondDegree (mcMathLine &p, const mcSymbolProperties *unk, mcSystemStepArray &steps)
 Solves equations of the second degree.
bool math_WorksOn (const mcMathOrSystem &m) const
 Checks that the given data contains a polynomial equation.
void math_FindPolyCoeff (const mcMathLine &data, const mcSymbolProperties *unk, int n)
 Fills the m_pCoeff array with the coefficient for the unk symbol, up to the n-th degree.
void math_GetPolyCoeff (mcMathLine &p, const mcSymbolProperties *unk, mcSystemStepArray &steps)
 A powerful version of math_FindPolyCoeff: simplifies, moves the data and calls automatically math_FindPolyCoeff.
bool math_isReady () const
 A mcPolySolver is always ready to work...
wxPanel * gui_GetOptionsPanel () const
 A mcPolySolver does not need any special setting.
