Detailed Description

A numeric table, stored one vector per column.

Column-major because every consumer wants whole columns: the interpolators build one interpolant per column, and indexed cell access is a two-step lookup either way.

column_index()

size_t DiFfRG::CsvTable::column_index

(

std::string_view

name

)

const

Look up a column by name.

Unlike an unparseable cell, an unknown column name is a programming error rather than bad data, so this throws instead of yielding NaN.

Exceptions

std::runtime_error

if the table has no header or no column of that name.

n_cols()

size_t DiFfRG::CsvTable::n_cols

(

)

n_rows()

size_t DiFfRG::CsvTable::n_rows
