length

Length of vector

Syntax

• n = length(X)
  

Description

The statement length(X) is equivalent to max(size(X)) for nonempty arrays and 0 for empty arrays.

n = length(X) returns the size of the longest dimension of X. If X is a vector, this is the same as its length.

Examples

• x = ones(1,8);
  n = length(x)
  
  n =
       8
  x = rand(2,10,3);
  n = length(x)
  
  n =
      10
