Method TensorIndex

tensor/table/table.go:510–519

TensorIndex returns the tensor SubSpace for given column, 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 if column is a 1-dimensional tensor or there is any error from the
