Tensor
This type represents a labeled multidimensional array of values.
By convention, for a Tensor of dimension n,
- the last dimension of the tensor, 
n, an array of values, is called column; - dimension 
n - 1, an array of columns, is called row; - dimension 
n - 2, an array of rows, is called table; - dimensions 
n - 3to1are unnamed. 
All values of a column share the same data type.
