: Use commands like colormap(parula) , colormap(jet) , or colormap(hot) to match your data type.
MATLAB provides several built-in functions to visualize 2D and 3D matrix data. Choosing the right function depends on the nature of your data. 2D Matrix Visualization
imagesc(A) : Scales data to use the full colormap. It is the most common tool for viewing images or heatmaps. Alternative (Older Versions) saveas(gcf, 'MatrixPlot
Plotting a matrix allows you to visualize patterns, outliers, and structures that raw numbers hide. Below are the three most effective plotting methods for xnxn matrices.
MATLAB offers several specialized plotting functions for visualizing square matrices. Each reveals different aspects of your data.
