Function Reference

ndims

Provide the number of the dimensions of an LTI model or LTI array

Syntax

• n = ndims(sys)
  

Description

n = ndims(sys) is the number of dimensions of an LTI model or an array of LTI models sys. A single LTI model has two dimensions (one for outputs, and one for inputs). An LTI array has 2+p dimensions, where is the number of array dimensions. For example, a 2-by-3-by-4 array of models has 2+3=5 dimensions.

• ndims(sys) = length(size(sys))
  

Example

• sys = rss(3,1,1,3);
  ndims(sys)
  ans =
       4
  

ndims returns 4 for this 3-by-1 array of SISO models.
