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 , 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. , one row for each discrete time instant.
