Add column vector to the end of another column vector

Hello! I have two rather large data sets that I am trying to combine into one data set. For example vector A is a 50x1 vector and vector B is a 100x1 vector. How do I combine these two togeher to get a 150x1 vector? Thanks so much!

A = rand(50,1); % example 50x1 vector
B = rand(100,1); % example 100x1 vector
C = vertcat(A,B) % concatenate A and B vertically

C = 150×1

0.6165 0.3890 0.8584 0.7299 0.1972 0.8609 0.3899 0.5217 0.3926 0.0891

Or:

C = [A; B];

Wonderful! Both of those worked great for me. I did some troubleshooting to see which would run faster because I my two data sets are over 4.5 million points

@Wilson Meireles, The methods are equivalent, just the syntax is different.

From the documentation of vertcat - "vertcat is equivalent to using square brackets to vertically concatenate or append arrays. For example, [A; B] is the same as vertcat(A,B) when A and B are compatible arrays."
