MATLAB vs Python vs R comparison - Interactive Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to create a vector of numbers from 1 to 5 in MATLAB.

MATLAB

vec = [1];

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

A[1 5]

B1:5

Crange(1,5)

Dseq(1,5)

Attempts:

3 left

💡 Hint

Common Mistakes

Using Python or R syntax like range() or seq() instead of MATLAB colon operator.

In MATLAB, the colon operator 1:5 creates a vector from 1 to 5.

2fill in blank

medium

Complete the Python code to create a list of numbers from 1 to 5.

MATLAB

lst = list(range(1, [1]))

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

A1,6

B5

C1,5

D6

Attempts:

3 left

💡 Hint

Common Mistakes

Confusing range parameters or using R or MATLAB syntax.

In Python, range(1,6) generates numbers from 1 to 5. The blank is the exclusive end parameter, so use 6.

3fill in blank

hard

Fix the error in this R code to create a sequence from 1 to 5.

MATLAB

seq_vec <- [1](1, 5)

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

Aseq

Brange

Clist

Dvector

Attempts:

💡 Hint

Common Mistakes

Using range instead of seq in R.

In R, seq(1, 5) creates a sequence from 1 to 5. The function range returns min and max, not a sequence.

4fill in blank

hard

Fill both blanks to create a 3x3 identity matrix in MATLAB and Python.

MATLAB

mat_matlab = [1](3);
mat_python = np.[2](3)

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

Aeye

Bidentity

Cones

Dzeros

Attempts:

3 left

💡 Hint

Common Mistakes

Using ones or zeros instead of identity matrix functions.

In MATLAB, eye(3) creates a 3x3 identity matrix. In Python with NumPy, np.identity(3) does the same.

5fill in blank

hard

Fill all three blanks to calculate the mean of a vector in MATLAB, Python, and R.

MATLAB

mean_matlab = [1](vec);
mean_python = statistics.[2](vec)
mean_r <- [3](vec)

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

Amean

Dmedian

Attempts:

3 left

💡 Hint

Common Mistakes

Using median instead of mean.

All three languages use mean function to calculate the average of a vector.
