当前状态线性化的MATLAB和Python代码_MATLAB and Python Code for Current S

The following m-files are included in this toolkit LinApp_FindSS - Takes a function, funcname.m, and a steady state value for the exogenous state variables as inputs. Finds the steady state for the model's endogenous state and jump variables. LinApp_Deriv - Takes a function, funcname.m, as an input. Generates the derivative matrices needed for the Uhlig toolkit. LinApp_Solve - Takes the derivative matrices as inputs. Uses the code from the Uhlig toolkit to generate the coefficients for the linearized policy function(s). LinApp_Sim - Takes the policy function coefficients and current state as inputs. Generates the value(s) of the endogenous state variables for the next period. LinApp_SSL - Takes a history of exogenous state variables and the policy function coefficients as inputs. Generates a history of state and jump variables using linearization about the steady state. LinApp_CSL - Takes a history of exogenous state variables as inputs. Generates a history of state and jump variables using linearization about the current state.
