com.opengamma.analytics.financial.model.option.pricing.analytic.formula.SABRExtrapolationRightFunction.priceAdjointSABR()
Computes the option price derivative with respect to the SABR parameters. The price is SABR below the cut-off strike and extrapolated beyond. @param option The option. @param priceDerivativeSABR An array of three doubles in which the derivative with respect to SABR parameters will be stored. The derivatives are w.r.t. [0] alpha, [1] beta, [2] rho, and [3] nu. @return The option derivative.
