Frequently Asked MATLAB Interview Questions
If you’re a beginner or a fresher, these MATLAB interview questions for beginners will help you prepare well.
MATLAB is one of the high-performance languages that is used for numerical computing. It consolidates programming, visualisation and calculations in an easy-to-use environment where answers and problems are showcased in familiar binary notation. It comprises
MATLAB API is a library that lets you write C and Fortran programs that interact with MATLAB. It comprises the facilities for calling MATLAB as a computational engine, reading and writing Mat files, and calling routines from MATLAB.
This is the set of facilities and tools that you work with as the MATLAB programmer or client. It comprises facilities to handle the variables in the workspace and import as well as export data. Furthermore, it also has tools for debugging, profiling M-files, managing, and developing MATLAB applications.
Simulink is MATLAB’s add-on product that offers a stimulating, interactive and graphical environment for analyzing and modelling dynamic systems.
In MATLAB, a polynomial is represented by a vector. To create it, you will have to enter every coefficient of the polynomial into the vector in descending order.
Handle Graphics is the graphic system of MATLAB. It comprises high-level commands for two and three-dimensional data visualisation, animation, image processing and display graphics. It also has low-level commands that let you customize the graphics’ display completely and develop a comprehensive Graphical User Interface on applications.
Get and Set are getter and setter functions in MATLAB. The getter functions are used for accessing features ,and the setter functions are used for assigning properties.
No, MATLAB cannot support multi-dimensional arrays. However, it can support the two-dimensional type of matrix.
MATLAB offers a variety of loops, such as:
The four essential functions that are used to solve ODE are:

If you’re a professional and have some knowledge of MATLAB, these MATLAB interview questions for professionals will help you sharpen your existing skills.
The 3D-Visualization elements let MATLAB handle 3D graphics, such as:
|Surface and Mesh Plots||It comprises visualized functions, plot matrices, and colour maps|
|Volume Visualization||It is generally used for the volume data grid|
|View Control||It is used to control the viewpoint of the camera along with rotation, zooming, and aspect ratio, as well as setting axis limit|
|Transparency||It is used to specify object transparency|
|Lighting||It is used to add and control scene lighting|
Here is the list of memory management functions in MATLAB:
|Clear||Removes variables from memory|
|Quit||Exits MATLAB and all of the allocated memory to the system|
|Pack||Saves the existing variables to the disk and reloads them continuously|
|Load||Reloads the data files stored with the save function|
|Save||Selectively persists variable to disk|
Here is the list of memory management functions in MATLAB:
|Errorbar||Plots error bars along the curve|
|Hold||Keeps the current graph and simultaneously adds a new graph|
|Line||Creates a line object|
|Line Specification (LineSpec)||Syntax of line specification string|
|Loglog||Log to the log-scale plot|
|Plot||2-D line plot|
|Plot3Ylim||3-D line plot|
|Plotyy||2-D line plots with y-axis on both the right and left sides|
|Polar||Polora coordinate plot|
|Subplot||Creates an axis in tiled positions|
|Xlim||Queries or sets x-axis limits|
|Ylim||Queries or sets y-axis limits|
|Zlim||Queries or sets z-axis limits|
M-files are plain ASCII scripts that are interpreted at run time. Basically, they are the subprograms stored in text files with a .m extensions. Furthermore, they are used for most of the development, maintainability and platform independence of MATLAB. It gets just-in-time compiled and is parsed once. However, it is transparent to customers as well.
By default, the code gets stored with the (.m) extension, which is anchored. However, if you need to put it away in a more anchored way, you can go with these methods:
MATLAB is generally used in space environments and aerospace engineering. It is adequate for flexible dynamics. The experts in the domain carry out stress analysis on a variety of operations, such as composite and metallic structures. To evaluate the stress, PATRAN, Oracle, IDEAD, and NASTRAN levels of proficiency are needed. The functions of the metallic structure are also used on aircrafts. The stress analysis primarily comprises the understanding of control surface stiffness, finite item modeling, loop evaluation, and fatigue testing analysis and requirements.
|Who||Shows all of the variables you have defined currently|
|Whos||Shows the variables, their sizes and additional information|
|pi||Refers to a function that returns the pi equation|
|eps||Refers to a function that returns the lowest floating-point number of MATLAB|
|Type||A function name for any function in the search path of MATLAB that allows you to see how the function is written|
Numeric Precision is when numeric quantities are presented as double-precision floating-point numbers. In systems, these numbers have 53 essential binary bits, which is approximately 15 or 16 decimal digits.
Pseudorandom binary sequence is a form of creating an M-file in the new Frequency Domain System Identification Toolbox for specific lengths (2^2-1 to 2^30-1). It is also known as Maximum Length Binary Sequence (mlbs).
Xmath is referred to as an interactive graphics and design environment for the workstations of Xwindows. Some of the key features of Xmath include:
Some of the basic and standard toolboxes in MATLAB are:
To create any of the toolboxes, you will have to:
And you are done.
