Practice - 5 Tasks

1fill in blank

easy

💡 Hint

Common Mistakes

Using 'function' keyword instead of '@(x)'

Trying to use Python or other language syntax like 'lambda' or 'def'

The @(x) syntax defines an anonymous function in MATLAB that takes x as input.

2fill in blank

medium

Complete the code to create an anonymous function that adds 5 to its input.

MATLAB

addFive = [1] x + 5;

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Omitting the '@' symbol

Using other language syntax like 'lambda'

Anonymous functions in MATLAB start with @(x) followed by the expression.

3fill in blank

hard

Fix the error in the anonymous function that multiplies input by 3.

MATLAB

triple = [1] x * 3;

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Using 'function' keyword

Using Python syntax like 'lambda' or 'def'

The correct way to define an anonymous function in MATLAB is with @(x).

4fill in blank

hard

Fill both blanks to create an anonymous function that returns true if input is greater than 10.

MATLAB

isGreaterThanTen = [1] x [2] 10;

Drag options to blanks, or click blank then click option'

A@(x)

B==

C>

D<

💡 Hint

Common Mistakes

Using equality operator instead of greater than

Omitting the '@(x)' part

The anonymous function starts with @(x) and uses the greater than operator > to compare.

5fill in blank

hard

Fill all three blanks to create an anonymous function that returns true if input is between 5 and 15 (inclusive).

MATLAB

isBetween = [1] x [2] 5 && x [3] 15;

Drag options to blanks, or click blank then click option'

A@(x)

B>=

C<=

D==

Attempts:

3 left

💡 Hint

Common Mistakes

Using strict greater than or less than instead of inclusive operators

Omitting the '@(x)' syntax

The function uses @(x) to define the anonymous function, and checks if x is greater than or equal to 5 and less than or equal to 15.
