The `repr_matrix`

computes matrix of representations from matrix of time series

1 2 |

`x` |
the matrix, data.frame or data.table of time series, where time series are in rows of the table |

`func` |
the function that computes representation |

`args` |
the list of additional (or required) parameters of func (function that computes representation) |

`normalise` |
normalise (scale) time series before representations computation? (default is FALSE) |

`func_norm` |
the normalisation function (default is |

`windowing` |
perform windowing? (default is FALSE) |

`win_size` |
the size of the window |

This function computes representation to an every row of a matrix of time series and returns matrix of time series representations.
It can be combined with windowing (see `repr_windowing`

) and normalisation of time series.

the numeric matrix of representations of time series
