MATLAB Fundamentals Certification Questions and Answers
- 1.
What does MATLAB stand for?
- A.
Matrix Laboratory
- B.
Mathematical Laboratory
- C.
Methodical Laboratory
- D.
None of the above
Correct Answer
A. Matrix LaboratoryExplanation
MATLAB stands for Matrix Laboratory. It was designed to provide easy access to matrix software developed by the LINPACK (linear system package) and EISPACK (Eigen system package) projects. MATLAB’s ability to manipulate matrices makes it a useful tool for linear algebra and numerical analysis.Rate this question:

What is the command to create a row vector of 1 to 10 in MATLAB?
- A.
1:10
- B.
1;10
- C.
1,10
- D.
1.1
Correct Answer
A. 1:10Explanation
In MATLAB, the colon operator (:) is used to create vectors of regularly spaced values. 1:10 creates a row vector with values from 1 to 10. This is a simple and efficient way to create a sequence of numbers in MATLAB.Rate this question:

How do you execute a group of statements in a loop while a condition is true in MATLAB?
- A.
For loop
- B.
While loop
- C.
Do loop
- D.
Switch loop
Correct Answer
B. While loopExplanation
In MATLAB, a while loop is used to execute a group of statements an indefinite number of times while a condition is true. This is useful when the number of iterations is not known in advance. The loop continues until the condition becomes false.Rate this question:

What function would you use to find the maximum element in a vector in MATLAB?
- A.
Max()
- B.
Min()
- C.
Sum()
- D.
Mean()
Correct Answer
A. Max()Explanation
The max() function in MATLAB returns the maximum element in an array or vector. This function is particularly useful when you need to find the highest value in a set of data. It can operate along any dimension of the array and return the maximum values of each column, row, or the entire array.Rate this question:

How do you add a comment in MATLAB?
- A.
//
- B.
#
- C.
%
- D.
--
Correct Answer
C. %Explanation
In MATLAB, the % symbol is used to add comments. Anything following the % on a line is considered a comment. Comments are used to explain the code and improve its readability. They are ignored by the MATLAB interpreter, so they do not affect the execution of the program.Rate this question:

What does the size() function do in MATLAB?
- A.
Returns the number of elements
- B.
Returns the maximum value
- C.
Returns the size of an array
- D.
Returns the minimum value
Correct Answer
C. Returns the size of an arrayExplanation
The size() function in MATLAB returns the size of an array. It returns a row vector whose elements are the lengths of the corresponding dimensions of the array. This is useful when you need to know the dimensions of an array, such as when you are performing matrix operations that require the matrices to be of certain dimensions.Rate this question:

How do you generate a matrix of zeros in MATLAB?
- A.
Zeros()
- B.
Ones()
- C.
Rand()
- D.
Eye()
Correct Answer
A. Zeros()Explanation
The zeros() function in MATLAB is used to create a matrix of zeros. The size of the matrix is specified as arguments to the function. This function is often used to initialize a matrix before filling it with values.Rate this question:

What does the .' operator do in MATLAB?
- A.
Matrix multiplication
- B.
Element-wise multiplication
- C.
Matrix division
- D.
Transpose of a matrix
Correct Answer
D. Transpose of a matrixExplanation
The .' operator in MATLAB performs the transpose of a matrix, interchanging its rows and columns. This operation is commonly used in linear algebra and data analysis to rearrange data and to compute certain types of matrix products.Rate this question:

- 9.
How do you solve linear equations in MATLAB?
- A.
Solve()
- B.
Roots()
- C.
\ operator
- D.
== operator
Correct Answer
C. \ operatorExplanation
The \ operator in MATLAB is used to solve systems of linear equations. It performs a left division operation, which is conceptually equivalent to multiplying the right-hand side of the equation by the inverse of the matrix on the left-hand side. This is a more efficient and numerically stable way to solve linear equations than computing the inverse directly.Rate this question:
-
- 10.
What does the end keyword signify in MATLAB?
- A.
The end of a statement
- B.
The end of a loop or conditional statement
- C.
The end of a function
- D.
All of the above
Correct Answer
D. All of the aboveExplanation
The end keyword in MATLAB signifies the end of a loop, conditional statement, function, or other block of code. It is used to define the scope of control structures and functions. Using end helps MATLAB to understand where to stop executing a particular block of code.Rate this question:
