Matrix Algebra and Scalar Multiplication with R and Rcpp

Matrix algebra is the mathematical backbone of modern data science, machine learning, and statistical computing. Understanding how to manipulate matrices and perform scalar multiplication efficiently is crucial when working with large-scale datasets. This course guides you from the fundamental mathematical definitions of matrix algebra directly into high-performance computational implementation. You will start by building a strong theoretical foundation, learning how scalars interact with matrices and why these operations matter. From there, you will write clean R code to perform these operations and quickly transition to Rcpp, which allows you to write high-performance C++ code directly within your R environment to handle intensive computations. What you'll learn: - Understand the core mathematical principles of matrix algebra and scalar multiplication - Implement matrix operations using native R syntax and data structures - Integrate C++ code into your R workflow using Rcpp to accelerate computations - Optimize matrix manipulation algorithms for memory and execution speed - Write clean, modern R code using robust type handling and performance best practices - Verify computational accuracy through structured written exercises and mathematical checks This course begins with essential terminology, mathematical definitions, and basic matrix concepts before moving into practical code implementations in R and performance optimization with Rcpp. You will progress from manual calculations to writing highly optimized, production-ready code. This course is designed for beginners in computational mathematics, data analysts, and R programmers who want to improve their mathematical computing skills and learn how to optimize their code. No prior experience with C++ or advanced matrix calculus is required. Start learning today and unlock the power of high-performance matrix operations in R.
