Description: Get the system of linear equations that calculate vertex limit point locations from the corresponding ring vertices's control net points. This information is useful when solving location interpolation problems. Parameters: m - [out] v - [out] The linear system of equations that calculates vertex limit points from vertex control net points is returned in matrix form: v[i]->SurfacePoint = sum(0 <= j < c) m[i][j]*v[j]->ControlNetPoint(). Returns: True if m and v were returned.

Description: Test the coefficients by using them to calculate the location of each limit surface point and returning the maximum deviation. Returns: ON_DBL_QNAN: Invalid information in coefficients or invalid vertices referenced. >= 0: Maximum deviation between a location returned by ON_SubDVertex::GetSurfacePoint() and the location calculated from the coefficients.
