MATLAB - 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.
Example
Create a script file with the following code −
r1 = [ 1 2 3 4 ]; r2 = [5 6 7 8 ]; r = [r1,r2] rMat = [r1;r2] c1 = [ 1; 2; 3; 4 ]; c2 = [5; 6; 7; 8 ]; c = [c1; c2] cMat = [c1,c2]
When you run the file, it displays the following result −
r = Columns 1 through 7: 1 2 3 4 5 6 7 Column 8: 8 rMat = 1 2 3 4 5 6 7 8 c = 1 2 3 4 5 6 7 8 cMat = 1 5 2 6 3 7 4 8
