rank(obj)

Return the number of dimensions of an array.

Note

This function is deprecated in NumPy 1.9 to avoid confusion with numpy.linalg.matrix_rank. The ndim attribute or function should be used instead.

Notes

In the old Numeric package, rank was the term used for the number of dimensions, but in NumPy ndim is used instead.
