static int DiCurveFitting< T1, T2 >::calculateCoefficients (  const T1 *  x,
const T2 *  y,
const unsigned int  n,
const unsigned int  o,
T3_ *  c
)  [inline, static]
 

calculate coefficients for resulting polynomial function.

T1 = type of x coordinates T2 = type of y coordinates T3_ = type of coefficients (and for internal calculations)

Parameters:
x array with x coordinates of given points
y array with y coordinates of given points
n number of entries in array (= points)
o order of polynomial function
c array to store the resulting coefficients (o+1 entries !)
Returns:
true if successful, false otherwise

T2 *  y,
const unsigned int  n,

const T3_ *  c
)  [inline, static]
 

calculate y coordinates for the given range of x coordinates.

The polynomial function is defined by the specified coefficients. T1 = type of x coordinates T2 = type of y coordinates T3_ = type of coefficients (and for internal calculations)

Parameters:
xs first x coordinate for computation
xe last x coordinate for computation
y array to store the resulting y coordinates (n entries !)
n number of entries in array (= points)
o order of polynomial function
c array of coefficients computed by the above method (o+1 entries !)
Returns:
true if successful, false otherwise
