# Computation of Global and Local Coefficients of Multiscale SBF Representation

### Description

This function generates global and local coefficients of multiscale SBF representation.

### Usage

1 | ```
mracoef.comp(coef, site, netlab, eta)
``` |

### Arguments

`coef` |
coefficients of the initial SBF representation |

`site` |
grid points of observation sites in radian |

`netlab` |
vector of labels representing sub-networks |

`eta` |
bandwidth parameters for Poisson kernel |

### Value

`beta` |
global coefficients of multiscale SBF representation |

`gamma` |
local coefficients of multiscale SBF representation. That is the detailed coefficients of SW |

`norm` |
norms of SW coefficients for sub-network |
