Here are the solutions to the questions: 12. The function that generates a row vector of evenly spaced values is C) linspace()* linspace(x1, x2, n) generates n points between x1 and x2 (inclusive). 13. One of the following commands creates a 3x3 zero matrix D) zeros(3,3)* The zeros(m,n) function creates an m × n matrix of zeros. zeros(3) would also create a 3 × 3 zero matrix. 14. What is returned by the command eye (3)? B) Identity matrix* The eye(n) function creates an n × n identity matrix. 15. Which indexing returns the second row of matrix A? B) A(2,:)* In MATLAB, A(row, column) is used for indexing. The colon : indicates all elements in that dimension. So, A(2,:) selects all columns of the second row. 16. One of these is a built-in MATLAB function. C) round()* round() is a standard built-in MATLAB function used to round numbers to the nearest integer. 17. function keyword is required to define a user-defined function in MATLAB. B) function keyword* User-defined functions in MATLAB begin with the function keyword. 18. User-defined functions can be saved at D) .m files* All MATLAB script and function files are saved with the .m extension. 19. One of the following keywords is used to terminate a function in matlab. B) end* The end keyword is used to terminate the definition of a function, if statements, for loops, and while loops in MATLAB. 20. One of the following is a function used to calculate the square root in MATLAB. B) sqrt()* The sqrt() function calculates the square root of a number. 21. The command used for basic 2D plotting is B) plot()* The plot() function is the primary command for creating 2D line plots in MATLAB. 22. Which function creates 3D surface plots? A) surf()* The surf() function creates 3D surface plots from matrix data. 23. Which command is used to label the x-axis of a graph in MATLAB? A) xlabel()* The xlabel() function adds a label to the x-axis of a plot. 24. Indicate how to hold a plot to add more data series? C) hold on* The hold on command retains the current plot in the axes so that new plots added to the axes do not delete existing plots. 25. title() is a function used to set the title of a plot? B) title()* The title() function adds a title to the current plot. 26. Which loop repeats a block a fixed number of times? D) for* A for loop is used when you know in advance how many times you want to execute a block of code. 27. The conditional statement used to check multiple conditions is termed as C) elseif* The elseif statement is used in conjunction with if and else to check multiple conditions sequentially. 28. The output of mod (9,4) is B) 1* The mod(a,n) function returns the remainder after division of a by n. (9)/(4) = 2 with a remainder of 1 Therefore, mod(9,4) is 1. Drop the next question! 📸
