💡 Hint

Common Mistakes

Using '=' instead of '==' for comparison.

Using '~=' which means not equal.

In MATLAB, == is used to compare if two values are equal.

2fill in blank

medium

Complete the code to check if variable x is greater than 5.

MATLAB

if x [1] 5
    disp('x is greater than 5');
end

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

B==

C<=

D<

💡 Hint

Common Mistakes

Using '<' which means less than.

Using '==' which means equal.

The operator > checks if the left value is greater than the right value.

hard

Fix the error in the code to check if y is not equal to 0.

MATLAB

if y [1] 0
    disp('y is not zero');
end

💡 Hint

Common Mistakes

Using '=' instead of '~='.

Using '==' which means equal.

The operator ~= means 'not equal' in MATLAB.

4fill in blank

hard

Fill both blanks to create a logical expression that checks if z is between 1 and 10 (inclusive).

MATLAB

if (z [1] 1) && (z [2] 10)
    disp('z is between 1 and 10');
end

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

💡 Hint

Common Mistakes

Using '>' instead of '>=' for the lower bound.

Using '<' instead of '<=' for the upper bound.

Use >= to check if z is at least 1, and <= to check if z is at most 10.

5fill in blank

hard

Fill all three blanks to create a dictionary (struct) comprehension that stores whether each number in nums is less than 5.

MATLAB

result = struct();
for i = 1:length(nums)
    result.[1] = (nums(i) [2] 5);
end
keys = fieldnames(result);
for k = 1:length(keys)
    disp([keys{k} ': ' num2str(result.(keys{k}))]);
end

💡 Hint

Common Mistakes

Using numbers directly as field names.

Using '>' instead of '<' for comparison.

We use num2str(nums(i)) as the field name, check if nums(i) < 5, and convert i to string for display.
