Method Tensor

tensor/table/table.go:526–538

Tensor returns the tensor SubSpace 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 nil on any error -- see Try version for error returns.

(column string, row int)

// being the row number.  Returns nil on any error -- see Try version for
// error returns.

		return nil
	}
	ct := dt.ColumnByName(column)
	if ct == nil {
		return nil
	}
	if ct.NumDims() == 1 {
		return nil
	}
	return ct.SubSpace([]int{row})

// TensorFloat1D returns the float value of a Tensor cell's cell at given
// 1D offset within cell, for given column (by name), row index
