MATLAB Grader is an online tool that allows educators to scale assessments, autograde assignments, and provide feedback. Using a single web browser, instructors can create and manage interactive course assignments, use an extensive library of reusable example courses and activities, and track student progress with detailed individual and aggregate analytics.
Unlike C++, which can be difficult to read and write, MATLAB is a concise programming language that makes it easy to understand and share code with others. It also enables users to perform symbolic math operations with a variety of tools and algorithms.
A MATLAB screen contains several panels, including a command window, workspace panel, current directory panel, and command history panel. The command window lets users run commands on variables and the workspace panel lets them define new variables.
MATLAB can also call functions written in a large number of languages. This allows users to share code across teams. It can also be used as a programming language for simulations. It also provides a number of different libraries, or toolboxes, to meet the needs of specific users.

Which MATLAB function reads a JSON file and converts it to a MATLAB structure?
Answer: A. jsondecode(fileread('data.json'))
MATLAB has no single jsonread function; the standard pattern is fileread() to get the raw text then jsondecode() to parse it into a struct.
What is the final value of the variable `total` after the following MATLAB code is executed? ```matlab total = 0; data = [10, -5, 20, 0, -15, 30]; for k = 1:length(data) if data(k) < 0 continue; end total = total + data(k); end disp(total); ```
Answer: A. 60
The `continue` statement skips the remainder of the current loop iteration and proceeds to the next one. When the loop encounters a negative number (-5 and -15), the `continue` command is executed, skipping the `total = total + data(k);` line for that iteration. Therefore, only the non-negative numbers are added: 10 + 20 + 0 + 30 = 60.
A script `mainScript.m` contains the following code: ```matlab % mainScript.m value = 10; modifyValue(value); disp(value); ``` The function `modifyValue` is defined in a separate file `modifyValue.m`: ```matlab function modifyValue(inputArg) inputArg = inputArg + 5; end ``` Assuming both files are in the current directory, what is displayed in the Command Window when `mainScript` is run?
Answer: B. 10
MATLAB passes arguments to functions by value. This means that when `value` is passed to `modifyValue`, a local copy of the variable is created within the function's workspace named `inputArg`. Modifying `inputArg` inside the function does not affect the original `value` variable in the script's (base) workspace. Therefore, the value of `value` remains 10.
Which MATLAB function evaluates a string as a MATLAB expression?
Answer: C. eval()
eval() executes the MATLAB code contained in a character vector or string.
