MATLAB: Taking the last value of a matrix or vector

last term of a vector with n rows

Hi. How can I take a last term of a vector – since my vector dimensions change -, and plug it in somewhere else in my code without keep changing the code?

for example right now I do v(6) to get the 6th term. How can I do it for nth term…. Thanks

Best Answer

v(end)

v(length(v))

java.lang.Thread.sleep(t*1000) than is more accurate than pause(t)

tic;
for i=1:20
  toc
  disp('test');
  java.lang.Thread.sleep((i-toc)*1000);
end

See http://undocumentedmatlab.com/blog/pause-for-the-better . But my measurements with pause look fairly accurate also.

Use a timer for triggering code after certain times.
