Function default_shape_for 

Source 
pub fn default_shape_for(shape: &[usize], len: usize) -> Vec<usize>
Expand description

Return a canonical 2-D shape for a tensor given its shape slice and element count.

  • Empty data (len == 0) → [0, 1] (MATLAB convention for empty arrays).
  • No shape info (shape.is_empty()) → [1, 1] (scalar).
  • Otherwise → the tensor’s own shape.
