This function load grid floor and generate the var-cov matrix via exponential function

1 | ```
iso_spatial_exp(dist.matrix, nugget, sill, ranges)
``` |

`dist.matrix` |
the a distance matrix generate from spatial_dist function |

`nugget` |
the nugget value of the var-cov function |

`sill` |
the sill(variance, sigma^2) of the var-cov function |

`ranges` |
the range value of var-cov function |

A matrix of var-cov matrix

1 2 | ```
D = spatial_dist(expand.grid(1:5, 1:5))
iso_spatial_exp(D, 0, 3, 1)
``` |
