How to read the last element of a vector in Matlab and Octave

To access the last element of a vector v without indicating the position in Matlab or Octave, the word "end" is indicated in round brackets.

v(end)

The term "v" is the name of the vector.

The word "end" is the last position in the index.

Matlab / Octave returns the value at the last index position of the vector.

Example

Define a vector with 5 elements

>> v=['a';'b';'c';'d';'e']

To access the last element, type

>> v(end)
ans = e

Matlab displays the content at the last position of the vector.
