MATLAB Functions and Flow Control 3

Question 1

What is a MATLAB anonymous function?

Accepted Answer

A short function defined inline using the @() syntax

Answer

Anonymous functions use the `@(args) expression` syntax and are defined inline without a separate file.

Question 2

Which of the following correctly creates an anonymous function that squares its input?

Accepted Answer

sq = @(x) x^2

Answer

The anonymous function syntax is `@(input_args) expression`, so `@(x) x^2` is correct.

Question 3

What does `nargout` return inside a MATLAB function?

Accepted Answer

Number of output values requested by the caller

Answer

`nargout` returns how many output arguments the caller requested when invoking the function.

Question 4

In MATLAB, what is a nested function?

Accepted Answer

A function defined inside another function's body

Answer

A nested function is defined within the body of another (parent) function and shares its workspace.

Question 5

How does MATLAB handle a `while` loop when the condition is false from the start?

Accepted Answer

Never executes the loop body

Answer

If the while condition is false initially, MATLAB skips the loop body entirely without executing it.
