The Jacobian of a robot refers to the matrix that linearly maps the velocity components of the end-effector and the velocities at the actuated joints. The Jacobian is extensively used in dimensional synthesis for Jacobian-based optimal performances of robotic manipulators, in which the optimal dimensional parameters of robots are computed. Determination of accurate mobility (Yang et al., 2008) of planar and spatial mechanisms can also be performed by using Jacobian in cases where Chebychev–Grübler–Kutzbach criterion cannot accurately determine the mobility (Gogu, 2005). As a result, Jacobian is a significant part for both kinematic analysis, dimensional synthesis and mobility determination of a mechanism. Hence, the formulation of Jacobian has its key importance in the literature and in the application of performance optimisation along with mobility computation. Formulation of Jacobian for serial manipulators can be computed easily, however, it is increasingly complicated to formulate Jacobian for parallel manipulators due to the existence of passive joint velocities and the nature in which these are related to active joint velocities. Several studies (Altuzarra et al., 2006; Dutre et al., 1997; D. Kim et al., 2000; S.-G. Kim &

Summary The greeks R package leverages the Black-Scholes model and more general jump diffusion models to compute sensitivities of financial option prices for European, geometric and arithmetic Asian, as well as American options, with various payoff functions (for a treatment see Hull (2022), and Angus (1999) for the case of geometric Asian options). The Black-Scholes model is the standard approach for modelling stock prices, while jump diffusion models aim to offer a more realistic representation of market movements, see Kou (2002). Furthermore, methods to compute implied volatilities are provided for a wide range of option types and custom payoff functions. Classical formulas are implemented for European options in the Black-Scholes model, as is presented in Hull (2022). In the case of Asian options, Malliavin Monte Carlo Greeks are implemented, see Hudde & Rüschendorf (2023), or Lyuu et al. (2019). For American options, the Binomial Tree method is implemented, as is presented in Hull (2022). greeks includes a Shiny app to interactively plot the results.
