What keyword is used to terminate a loop or switch statement early in MATLAB?
Answer: break
The `break` statement immediately exits the innermost for or while loop.
What does the `nargin` function return inside a MATLAB function?
Answer: Number of input arguments passed by the caller
`nargin` returns the number of input arguments actually provided when the function was called.
Which syntax correctly defines a MATLAB function that returns two output values?
Answer: function [a, b] = myfunc(x)
Multiple return values are declared with square brackets: `function [a, b] = myfunc(x)`.
In a `switch` statement, what block handles all cases not matched by any `case`?
Answer: otherwise
The `otherwise` block in a MATLAB switch statement handles unmatched cases.
What happens when `continue` is used inside a for loop in MATLAB?
Answer: Skips to the next iteration
`continue` skips the remaining statements in the current iteration and proceeds to the next one.
Which MATLAB function allows you to call a function by its name stored as a string?
Answer: feval()
`feval('funcname', args)` evaluates the named function with the given arguments.
What is the output of the following code? for k = 1:3 if k == 2, continue; end disp(k) end
Answer: 1 3
`continue` skips `disp(k)` when k==2, so only 1 and 3 are displayed.
