Parameter Description

Parameter Description

Nth Dimension of Processed Variables in Vector

Description: This parameter specifies the nesting hierarchy of lengths to be counted (starting from 0 and ending at 14).

  • When the input is a one-dimensional list, setting the dimension to 0 indicates counting the elements of the list.

  • When the input is a multidimensional nesting structure, the dimension value represents the corresponding nesting hierarchy. The dimension value should be smaller than the actual number of nesting hierarchy levels of the data.

Default value: 0
