Method TensorFloat1D

tensor/table/table.go:546–563

TensorFloat1D returns the float value of a Tensor cell's cell at given 1D offset within cell, for given column (by name), row index for columns that have higher-dimensional tensors so each row is represented by an n-1 dimensional tensor, with the outer dimension being the row number. Returns 0 on a

(column string, row int, idx int)

// being the row number.  Returns 0 on any error -- see Try version for
// error returns.
func (dt *Table) TensorFloat1D(column string, row int, idx int) float64 {
	if !dt.IsValidRow(row) {
		return 0
	}
	ct := dt.ColumnByName(column)
	if ct == nil {
		return 0
	}
	if ct.NumDims() == 1 {
		return 0
	}
	_, sz := ct.RowCellSize()
	if idx >= sz || idx < 0 {
		return 0
	}
	off := row*sz + idx
	return ct.Float1D(off)
}
