Utility class to compute a curve parameter defined by f(t)=0.

f(t) is defined by "virtual double operator()=0;". To use MGCurveParameter class, define subclass of MGCurveParameter, and define operator(). Then use getCurveParameter member function to compute the solution of f(t)=0. Before using getCurveParameter(), the tolerance and the incremental value must be set. These default values provided in the constructor are usually not valid ones.

MGCurveParameter::MGCurveParameter ( const MGInterval &  prange, double  error = .001, double  delta = 5.  )

inline

constructor. error and delta must be set if not specified in this constructor. Following default values are usually not effective.

引数

prange	parameter range for the computation.
error	tolerance to compute the parameter value(for f(t)).
delta	incremental value for the curve parameter.

関数詳解

int MGCurveParameter::getCurveParameter

(

double &

t

)

Get the paramer value of f(t)=0 that is defined by operator()(double)=0. Function's return code is: 0: when the solution is successfully obtaine in t, 1: There is no solution. -2:system error(usually this does not occur. If occured, some bugs are included.)

引数

t	input the guess parameter, the exact solution will be returned when function's return value is 0.

virtual double MGCurveParameter::operator() ( double  t ) const

pure virtual

return the function value f(t) to solve f(t)=0.
