How to convert row vector into the column vector using matlab.

by Posted on

You can use the transpose method to change the row vector into a column vector.

>> A = [1  9  3  7  3] 

>> B = A'

B =

    1

    9

    3

    7

    3

2. How to convert a column vector into the row vector?

Same as above use transpose method to change the column vector into a row vector.

>> C = B' C 

       = 1 9 3 7 3

The result on the MATLAB window:

Transpose is a simple and most common operation you can perform on MATLAB vectors.

Now, let us see, some other mathematical functions for arithmetic operation.

MATHEMATICAL OPERATIONS ON VECTOR

In the last post, I have explained the multiple Mathematical functions and their syntax in MATLAB.

These mathematical functions and their syntax are useful in the vector operation as well.

1. Arithmetic Operation of Vector:

The basic arithmetic operation consists of the addition (+), subtraction (-), multiplication (*), etc.

Here, I am doing some basic mathematical operations.

For Example:

>> A = [7 5 33 61];

>> B =[21 3 1 4];

>> Addition of two vector A and B

>> X = (A + B)

X = 
   28 8 34 65

>> Substraction of two vector A and B

>> Y = (A-B)

Y =
    -14 2 32 57

>> Mutliplication of vector

>> z=(4*y)

z =
   -56 8 128 228

The result on MATLAB display:

2. Length of Vector:

Length function is useful for calculating the number of elements in the vector.

In the MATLAB, there is a length method.

Example:

How to calculate the length of the vector in MATLAB?

Here is a syntax.

>> X = [2 4 1 7 8];

>> length(X) 

= 5

The Result on MATLAB display:

3. Square and Cube (power) of the Vector:

In MATLAB, ‘.^’ (Dot power) is used for calculating the square and cube (or power) of the vector.

Example:
