In the previous section, Vedic square was introduced as multiplication table of digital roots. Vedic square has very rich patterns that worth to explore further about its properties.
General Vedic square can have any size bigger than 9 by 9. We can then derive several important basic properties for general Vedic square of any size
Many 2 dimensional patterns can be generated using Vedic square, including many Islamic Arts (Jones, 1998). By putting some color to the numbers, we can make many patterns. Below is some example of a few patterns. You can download the MS Excel companion of this article here to try your own pattern.
The function below is useful to obtain Vedic Square using Matlab
function V=Vedic(n, color)
if nargin<1 | n<9, n=9; end % if no input or input less than 9, set n as 9
if nargin<2, color='prism'; end % if no input color set color as prism
A=[1:n]; % this is to make n by n Vedic square
V=K+mod((A'*A-K),9); % this is the Vedic square
imagesc(V); % show Vedic square as image
colormap(color); % change color of image. % Try many different color maps % such as 'colorcube', 'flag', 'hsv(30)', % 'jet', 'summer', 'hot', 'prism', etc.
axis off; % remove the axis label

In the next section, you will learn about the grouping or cluster of digital root pattern based on multiplication and division tables.
