Hi Shagun,

The following documentation link might be helpful to interpret the result of PCA biplot:

https://www.mathworks.com/help/stats/pca.html#btjpztu-1

You can refer to the section under the biplot command in the documentation page for more details:

biplot(coeff(:,1:2),'scores',score(:,1:2),'varlabels',{'v_1','v_2','v_3','v_4'});

Hope this helps!
