Could you please elaborate on the concept of "the rank of injective" for me? I'm interested in understanding how it applies in the realm of mathematics, particularly in the context of functions and mappings. Could you explain what it signifies and how it is determined? Is there a specific formula or procedure used to calculate it? Also, would you mind giving some examples to illustrate the concept? It would be helpful if you could provide insights into its practical applications, if any, in the field of cryptocurrency and finance. Thank you for your assistance.

Conversely, when discussing the rank of a matrix in the context of surjective functions, we encounter a different perspective. A matrix A is surjective, or "onto," when its rank equals the number of its rows, m.

In the case of a surjective matrix, we refer to it as having "full row rank." This terminology underscores the fact that the matrix's rows are linearly independent and span the entire target space.

On the other hand, the injectivity of a matrix, or its "one-to-one" nature, is determined by a different criterion. A matrix A is injective if and only if its rank equals the number of its columns, n.

When a matrix possesses this property, we say that it has "full column rank." This signifies that the matrix's columns are linearly independent and that each unique combination of column vectors maps to a distinct point in the output space.
