Matrix Transposition

Explore how to transpose matrices efficiently in R using the base t() function and in C++ with Rcpp implementations. Understand the algorithmic approach to matrix transposition and verify results using popular C++ libraries Armadillo and Eigen. This lesson equips you with practical skills to handle matrix transposition coding and validation.

Matrix transposition 𝐴𝑇𝐴^𝑇 transforms the original matrix rows into columns so that a (𝑚×𝑛)(𝑚 \times 𝑛) matrix is transposed into (𝑛×𝑚)(𝑛 \times 𝑚), like so:

𝑎𝑖𝑗𝑇=𝑎𝑗𝑖𝑎^𝑇_{𝑖𝑗} = 𝑎_{𝑗𝑖} ...
