# Step-By-Step Guide to Plot Real and Imaginary Parts in MATLAB

MATLAB is a renowned software used in many fields such as mathematics, engineering, finance, and computer science. Itfeatures an extensive range of tools and features to assist proficient data plotting, analysing and manipulation.

In this document, we will learn how to plot real and imaginary parts in MATLAB with a step-by-step solution.

## Step 1: Set up a Vector

In order to plot real and imaginary parts in MATLAB, we need to set up a vector. This is a column-vector that contains real and imaginary parts in the range of 0 to 10.

Firstly, you need to open the "Command Window" and type `start RealImagVectors`. Then run it to display the code in the editor.

``````x=0:0.1:10;
a=[x;x];
b=[-x;x];

plot(a(1,:),a(2,:));
title('Real Parts');
xlabel('Real Values');
ylabel('Imaginary Parts');

plot(b(1,:),b(2,:));
title('Imaginary Parts');
xlabel('Real Values');
ylabel('Imaginary Parts');
``````

## Step 2: Running the Code

Once you have the API script in the editor, the next step is to run it. To do this, click on the "Run Button" in the editor window. This will display two plots in the command window. The first one will show the real parts of the vector and the second plot will display the imaginary parts.

## Step 3: Understanding the Graphs

The, two graphs displayed in the command window will help you understand the real and imaginary parts of the vector. The x-axis of the plot corresponds to the real values, while the y-axis of the graph corresponds to the imaginary parts. You can observe how the real and imaginary parts of the vector change with the increase in x values.

## FAQ

### What is a Vector?

A vector is an array of numbers or variables that can be used to store and traverse data. Vectors can be both real and imaginary.

### What is MATLAB?

MATLAB is a high-level programming language for numercial computing that combines data computation, algorithmic development, application development and graphic modelling.

### What is the Difference Between Real and Imaginary Vectors?

Real vectors contain values that represent actual quantities, whereas Imaginary vectors contain values which cannot be found in reality.

### What is Meant by Plotting Real and Imaginary Parts in MATLAB?

Plotting real and imaginary parts in MATLAB is to represent a set of numerical data with a graphical representation. It is used to gain insights into the relationship between the two parts of the data.

### How do I Plot Real and Imaginary Parts in MATLAB?

In order to plot real and imaginary parts in MATLAB, you need to set up a vector, run the script and then understand the graph. First, open the “Command Window” and type `start RealImagVectors`, then run it to display the code in the editor. Once you have the API script in the editor, the next step is to run it. Finally, you can observe how the real and imaginary parts of the vector change with the increase in x values.
