Method Float

tensor/table/table.go:458–470

Float returns the float64 value of cell at given column (by name), row index for columns that have 1-dimensional tensors. Returns NaN if column is not a 1-dimensional tensor or col name not found, or row not valid.

(column string, row int)

// for columns that have 1-dimensional tensors.
// Returns NaN if column is not a 1-dimensional tensor or col name not found, or row not valid.
