how do i print the length of a vector?? so i have a vector V = [4,9,-3,12,0,-9,15,17,25,-6,4,10,-2,15] and i got its length by L = length (V) now how do i print the length?

fprintf('Length of vector is %d\n', length(V))
The " %d " specifies that the number to be printed is an integer which should always be the output of length().
The " \n " specifies that a new line should be started after this text.

Note: another option that may be more intuitive for beginners
disp("Length of vector is " + length(V))
I'd recommend using numel rather than length. Many people misuse length.
