Below are few major features of Matlab
Q1. What is Matlab and why it is used?
Matlab expanded as Matrix Laboratory is a programming environment developed by Mathworks that is used for manipulating data, implementing algorithms, creating UI, etc. Released in 1984, Matlab uses Matlab programming language that allows natural expression for mathematical computation. Mainly used by engineers and scientists around the world to do a range of applications like Machine learning, signal processing, image & video processing, computational finance, etc. The main reason why Matlab is widely used are,
Q2. Enlist few application of matlab in mathematics?
Matlab works well in Mathematics. Some of the applications are,
Linear Algebra calculations can be done easily with Matlab. Eg: to calculate ROI, predicting the results, etc
The numerical Analysis task is heavily used by architects, engineers, etc which relies on approximation. These mathematical tasks are easily done in Matlab.
Processing image involves a lot of matrix computations which it easy handles by Matlab because of its extensive use of vector and matrix computations.
The Math function in Matlab provides functions to do Linear Algebra, Geometry, Fourier analysis, Integration & Differential equations, etc.
Matlab provides various functions to make the graph plotting a simple and easy task
Q3. What is Matlab API?
Matlab provides lots of API (Application Programming Interface) for library and code written in other languages to integrate with it. The API allows C, C++, FORTRAN programs to interact with Matlab. It is also used for dynamic linking, calling Matlab as a computational engine, and to read & write MAT files.
Some of the API’s in Matlab is,
MATLAB Engine API – used to interface c++, object-oriented programming, java, python in Matlab.
MATLAB Data API – used for other applications that work with Matlab data.
MATLAB MEX API – used to call c, c++, FORTRAN programs from Matlab command line.
Q4. List some real time applications of matlab?
Matlab has numerous applications in real life such as in
Q5. What are different types of loops available in Matlab?
Matlab provides various loop types to handle the looping requirement,
It repeatedly executes a statement until the expression becomes false.
It allows you to write a repetition control structure that can be executed a specific number of times.
Matlab allows for the loop to be executed inside another loop. It is called a nested loop.
Q6. List some numerical data type available in Matlab?
List some numerical data type available in Matlab
By default, Matlab stores value as a double-precision floating-point.
Q7. List out major operators of MatLab?
Some list major operators of MatLab
Q8. What is Simulink in MatLab?
Simulink is a graphical programming environment based on MATLAB. It is used for simulating and modeling systems integrated with the Matlab. The incorporation of algorithms in Simulink is also possible. The simulated models can be verified and validated using style checking, traceability, etc. From the model, code can be also automatically generated using the Simulink. It can be defined as a graphical block diagramming tool with its block libraries.
Q9. What is LaTex in MatLab?
LaTex is a document preparation system. Documents written using LaTex look much better because it uses iterative typesetting algorithm. Matlab supports LaTex using function latex ().
Syntax chr = latex(S) //chr reurns LaTex form of the expression S.
You can use Matlab to format mathematical expressions and text.
Q10. What is Set and Get in Matlab?
Set is a function in Matlab that is used to set the properties for the object.
Here H is the object where the value of the property Name is applied.
The object H is applied with the color blue.
Get is a function that returns the property of an object.
A = get(H)
Here the property of the object H is returned to the variable H.
