Matrix Multiplication Practice in R and Rcpp

Understanding how to perform and optimize matrix operations is a core skill for data analysis, statistical modeling, and scientific computing. This text-based course helps you build a solid foundation in matrix multiplication, transitioning from standard R implementations to high-performance C++ integration. You will learn how to write clean, efficient code and verify your understanding through structured written exercises. By completing this course, you will be able to confidently manipulate matrices, identify bottlenecks in your data workflows, and accelerate your computations using compiled code. What you'll learn: - Understand the mathematical foundations of matrix multiplication and linear algebra concepts - Implement standard matrix multiplication using native R syntax and functions - Write efficient C++ code using Rcpp to accelerate matrix operations - Compare performance differences between interpreted R code and compiled Rcpp code - Practice debugging and validating matrix dimensions to prevent runtime errors - Apply memory management best practices when passing matrices between R and C++ The course begins with foundational definitions of matrix properties and dimensions before guiding you step-by-step through standard R implementations. You will then progress to writing, compiling, and testing optimized Rcpp functions using clear, written code examples and self-paced practice problems. This course is designed for beginners in R or Rcpp who want to deepen their understanding of linear algebra computations. No advanced programming experience is required.
