# Put vectors with different length into NaN vectors with allways the same length

Hey guys,
I have a lot of data vectors wich have a different length. I want to compare them, to do so i have to normalize them. To normalize they need to have the same length.... So i wrote a loop to put the data vectors into a NaN-vector which has allways the same length.
My Problem is that the loop need pretty long depending on the size of 44100 NaN positions:
clc
clear all
Fs = 44100
V1 = NaN(Fs,1)
for i= 1:length(x)
V1(i,1) = x(i,1)
end
Is there an option to do that much faster ? Or is there another way to fill the data vectors with NaN so they have the same length?
Thank you!

Hi, the for loop is not required, you can achive the same assignment simply by:
V1(1:length(x),1) = x;
