MATLAB Basics
Basics on π
π is also called as Archimedes' constant. The historically first exact formula for π, based on infinite series, was not available until a millennium later, when in the 14th century the Madhava-Leibniz series was discovered in Indian mathematics.
Basics on Vectors
These problems test the basic skills on vector processing.
Basics - Rounding
These problems will test the skills in rounding.
CUP Challenge
Problems developed by MathWorks in collaboration with Cambridge University Press publishers.
Introduction to MATLAB
New to Cody? Start solving simple MATLAB problems that will test your basic MATLAB skills. If you are new to MATLAB, you can start with MATLAB Onramp, which is a two-hour introductory tutorial on commonly used MATLAB features and workflows.
Basics - Cell Arrays
Cell Arrays can contain data of varying types and sizes. Questions in this group will challenge your understanding about Cell Arrays.
MATLAB Onramp Practice
Practice your introductory MATLAB skills with these simple coding problems. These problems are based on the skills you learn in MATLAB Onramp, a free, two-hour tutorial on introductory MATLAB features and workflows.
Basics - Binary Logic
The modern binary number system was studied in Europe in the 16th and 17th centuries by Thomas Harriot, Juan Caramuel y Lobkowitz, and Gottfried Leibniz. However, systems related to binary numbers have appeared earlier in multiple cultures including ancient Egypt, China, and India. Leibniz was specifically inspired by the Chinese I Ching.
Basics - Triangles
Triangle based interesting problems are presented in this group.
Beyond the Basics
Indexing II
More problems that require operating on a subset of elements from a vector or matrix.
Sequences & Series II

Strings II
String together characters in the correct case.
Matrix Patterns II
Create even more patterned matrices.
Matrix Manipulation II
If only moving things around in real life were this easy.
Number Manipulation II
Manipulate more numbers from one form to another.
Matrix Manipulation I
Test your knowledge of matrix manipulations such as shift, flip, and transpose to solve these problems.
Project Euler I
Solve Project Euler problems using MATLAB.
Project Euler II
More problems inspired by Project Euler.
