com.opengamma.analytics.math.interpolation.PiecewisePolynomialResult
Result of interpolation by piecewise polynomial containing _knots: Positions of knots _coefMatrix: Coefficient matrix whose i-th row vector is { a_n, a_{n-1}, ...} for the i-th interval, where a_n, a_{n-1},... are coefficients of f(x) = a_n (x-x_i)^n + a_{n-1} (x-x_i)^{n-1} + .... In multidimensional cases, coefficients for the i-th interval of the j-th spline is in (j*(i-1) + i) -th row vector. _nIntervals: Number of intervals, which should be (Number of knots) - 1 _order: Number of coefficients in polynomial, which is equal to (polynomial degree) + 1 _dim: Number of splines
