{wiki=Simple_matching_coefficient}
The Simple Matching Coefficient (SMC) is a statistic used to measure the similarity between two sets or binary vectors. It provides a way to quantify the degree of similarity based on the presence or absence of certain characteristics. For binary vectors \\( A \\) and \\( B \\), each of length \\( n \\): - \\( a \\) is the number of features that are present in both \\( A \\) and \\( B \\) (i.e., both vectors have a value of 1).
