How To Create Vectors In MatLab®(Illustrated Expression)

This text shows how to obtain vectors in Matlab® and how to create vector variables in Matlab® codes. As its name implies, Matlab® generally works with the base of matrices. Also, vectors are matrices and you could do various matrice calculations with your created vector in Matlab®. Also, you could do mathematical calculations with Matlab® vectors and you could insert the Matlab® vector to mathematical calculations with other matrices, vectors, and individual variables. This is much easier in Matlab® coding compared with other software languages.

How Is The Creation Of Vectors In Matlab®?

v = [1 0 0]
d = [1; 2; 3]
z = 1:.5:3
p = pi*[-4:2:4]/4

There are a bunch of vector examples in the Matlab® script above, we will talk about their working principles below.

>> v = [1 0 0]
d = [1; 2; 3]
z = 1:.5:3
p = pi*[-4:2:4]/4

v =

     1     0     0


d =

     1
     2
     3


z =

    1.0000    1.5000    2.0000    2.5000    3.0000


p =

   -3.1416   -1.5708         0    1.5708    3.1416

As you can see the v vector is very basic and shows how to create a vector in Matlab® in principle. d vector shows how to create column vectors in Matlab®. You could understand that if you put ‘;’ between vector numbers, this vector will be a column vector like d. The meaning of z vector, ve create the z vector starts with 1, ends with 3, and increment of each element in z vector is 0.5. You could type the first value, increment value, and end value to create a vector by putting ‘:’ between these values.

In p vector, we did a bunch of mathematical calculations by using a vector-like z. As you can see we multiplied an increment vector with pi and divided it with 4.
