✍️ Sample MATLAB Questions & Answers
1. Which function in MATLAB computes numerical integration using adaptive quadrature?
The integral function uses adaptive Gauss-Kronrod quadrature to numerically integrate a function over a specified interval.
2. How do you load only the variable 'score' from 'results.mat' into the workspace?
Both the command syntax `load results.mat score` and the function syntax `load('results.mat', 'score')` are valid in MATLAB.
3. Which of the following correctly accesses the element in row 2, column 3 of matrix M?
MATLAB uses parentheses for indexing, so M(2,3) retrieves the element at row 2, column 3.
4. Which statement correctly defines a function that takes no inputs and returns no outputs in MATLAB?
A zero-input, zero-output MATLAB function uses `function functionName()` with empty parentheses.
5. Which MATLAB function creates a 3D surface plot from X, Y, Z grid data?
surf creates a shaded 3D surface using X, Y, Z grid matrices, with face colors representing Z values by default.
6. What is the role of the 'Tag' property in MATLAB UI components?
Tag is a user-defined string identifier that findobj can search for to retrieve a handle without storing it explicitly.
