Introduction In the world of computational mathematics and data science, the term "xnxn matrix" often refers to an n-by-n square matrix (where 'x' denotes multiplication, and 'n' is a variable representing size). Handling such matrices efficiently is a cornerstone of programming in MATLAB, a high-level language favored by engineers and researchers for matrix operations. % Step 3: Plot as heatmap h_fig =
