What Are Some Most Important Matlab Interview Questions?

MATLAB is a high-performance language widely used in technical operations. As a student of this field, students must know the subject that will be helpful to make a bright future. 

We are here with an essential set of interview questions related to data science and machine learning. Here are some frequently asked questions for Matlab interviews with answers that will help students prepare better. Read the complete article to know more on the same; if you need any help, seek MATLAB Assignment Help.

1. What is MATLAB?

MATLAB stands for MATrix LABoratory, an open-source software/API that was initially developed for mathematical calculations, doing matrix operations. The current version of the Matlab software can perform various complex calculations such as visualization, scientific, data analysis and engineering graphics etc. Its prime features also include simulation and modelling.

1. How to plot a graph in MATLAB?

For any two given points, x and y, with specific given values, a function called plot (x, y).

Syntax :   y : [value of array];

                 x : [value of array];

                 plot(x, y)

1. What is MATLAB used for?

MATLAB is a high-level matrix language. It has control structures, input/ output, functions, data structures, and OOP features. MATLAB API allows users C and FORTRAN programs to interact with MATLAB. It is also used in several industry levels, such as designing processes and running the control systems, automation of different machines by defining a special set of codes for an object.

• How one can read an image in MATLAB from a folder?

The syntax used to read image from any folder is given as:-

S = dir(fullfile(D,’name*.jpg’)); 

D = ‘directory where the files are saved;

for k = 1:numel(S)

    F = fullfile(D,S(k).name);

    I = imread(F);

    imshow(I)

    S(k).data = I; % optional, save data.

End

1. How to execute a neural network in MATLAB Software?

 A neural network is an adaptive system widely used to interconnect nodes or neurons in a layered structure that resembles a human brain. A neural network can learn from data to recognize patterns, forecast future events and classify data. 

The workflow of the design process has seven primary steps:-

1. Collect data
2. Create the network
3. Configure the network
4. Initialize the weights and biases
5. Train the network
6. Validate the network (post-training analysis)
7. Use the network

• How to stop a program in MATLAB?

You can use the quit command to stop a program in MATLAB, or you can use the desktop shortcut such as Ctrl + C. 

1. How to import data of Matlab in EXCEL

Simply click on the Import Data icon under the Home tab and navigating to the Excel file you want to import. 

• What are 3D-Visualization elements in MATLAB?

 3D-visualization elements let MATLAB deal with the 3D graphics. These are many 3D visualization elements in MATLAB:-

• Lightening – add and control the scene lighting.
• Transparency – Used to specify object transparency.
• Surface and Mesh plots – Includes colour maps and plot matrices
• Volume visualization – Used for the volume data grid.

• How can one write for loop in MATLAB?

Here is an example on ‘for loop’ in MATLAB :-

A = [3 6 9 4 1];

for i = 1:length(A)

       disp(A(i))

end

A loop is used to assign to or access array elements iteratively.

Hope these questions will help students understand the core concepts and fundamentals of Matlab better to prepare better for the interview. For more learning and knowledge content on Data Science and Machine, students can ask assistance from the assignment help provider.
