mathematical_model_eval | R Documentation |

This function evaluates the mathematical model at given observed inputs and calibration parameters.

mathematical_model_eval(input,theta,simul_type, emulator, emulator_type,loc_index_emulator,math_model)

`input` |
a matrix of the observed inputs. |

`theta` |
a vector of calibration parameters. |

`simul_type` |
tpye of math model. If the simul_type is 0, it means we use the RobustGaSP R package to emulate the math model. If the simul_type is 1, it means the function of the math model is given by the user. When simul_type is 2 or 3, the mathematical model is the geophyiscal model for Kilauea Volcano. If the simul_type is 2, it means it is for the ascending mode InSAR data; if the simul_type is 3, it means it is for the descending mode InSAR data. |

`emulator` |
an S4 class of rgasp model from the RobustGaSP R Package. |

`emulator_type` |
a character to specify the type of emulator. 'rgasp' is for computer models with scalar-valued output and 'ppgasp' for computer models with vectorized output. |

`loc_index_emulator` |
a vector of the location index from the ppgasp emulator to output. Only useful for vectorized output computer model emulated by the ppgasp emulator. |

`math_model` |
a function for the math model to be calibrated. |

a vector of outputs from the math model or its emulator at given observed inputs and calibration parameters.
