Purpose 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

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

ndims(sys) = length(size(sys))

Example sys = rss(3,1,1,3);

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

See Also size Returns a vector containing the lengths of the

dimensions of an LTI array or model
