Appending Vectors

MATLAB allows you to append vectors together to create new vectors.

If you have two row vectors r1 and r2 with n and m number of elements, to create a row vector r of n plus m elements, by appending these vectors, you write:

r = [r1,r2]

You can also create a matrix r by appending these two vectors, the vector r2, will be the second row of the matrix:

r = [r1;r2]

However, to do this, both the vectors should have same number of elements.

Similarly, you can append two column vectors c1 and c2 with n and m number of elements. To create a column vector c of n plus m elements, by appending these vectors, you write:

c = [c1; c2]

You can also create a matrix c by appending these two vectors; the vector c2 will be the second column of the matrix:

c = [c1, c2]

However, to do this, both the vectors should have same number of elements.
