👉 In mathematics, a rank is a property of a vector space or module. It is a measure of how many linearly independent vectors in that space are required to span it. In other words, if we have an n-dimensional vector space V with n linearly independent vectors {v1, v2, ..., vn}, then the rank of V is defined as n-1. For example, consider the vector space R^3 (the set of all 3-dimensional real numbers). The vectors
