bdm::CsvFileDS Class Reference

CSV file data storage The constructor creates Data matrix from the records in a CSV file fname. The orientation can be of two types: 1. BY_COL which is default - the data are stored in columns; one column per time $t$, one row per data item. 2. BY_ROW if the data are stored the classical CSV style. Then each column stores the values for data item, for ex. $[y_{t} y_{t-1} ...]$, one row for each discrete time instant. More...
