Multiple outputs in MATLAB - Interactive Code Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to define a function that returns two outputs.

MATLAB

function [a, b] = myFunc(x)
    a = x + 1;
    b = x[1]2;
end

💡 Hint

Common Mistakes

Using '+' instead of '*' will add 2 instead of doubling.

Using '/' will divide x by 2, which is incorrect here.

The function returns two outputs: 'a' is x plus 1, and 'b' is x multiplied by 2.

Complete the code to call the function and get both outputs.

MATLAB

[out1, [1]] = myFunc(5);

💡 Hint

Common Mistakes

Using only one output variable will ignore the second output.

Using a variable name that does not match the function outputs can cause confusion.

The function returns two outputs, so we capture the second output in 'out2'.

3fill in blank

hard

Fix the error in the function definition to correctly return two outputs.

MATLAB

function [1] = myFunc(x)
    a = x + 1;
    b = x * 2;
end

💡 Hint

Common Mistakes

Using parentheses or braces instead of square brackets causes syntax errors.

Omitting brackets leads to only one output being returned.

In MATLAB, multiple outputs are enclosed in square brackets in the function definition.

4fill in blank

hard

Fill both blanks to create a function that returns the sum and product of two inputs.

MATLAB

function [[1], [2]] = sumProd(x, y)
    [1] = x + y;
    [2] = x * y;
end

💡 Hint

Common Mistakes

Using 'sum' or 'prod' as variable names can conflict with MATLAB functions.

Mismatching output names in the function signature and body causes errors.

The function returns two outputs named 's' for sum and 'p' for product.

5fill in blank

hard

Fill all three blanks to call the function and display both outputs.

MATLAB

[[1], [2]] = sumProd(3, 4);
disp(['Sum: ', num2str([3])]);

💡 Hint

Common Mistakes

Using the wrong variable in disp causes incorrect output display.

Not converting number to string before concatenation causes errors.

We assign outputs to 'sumVal' and 'prodVal', then display the sum using 'sumVal'.
