👉 The term "catenate" in mathematics refers to a process of combining two or more matrices or vectors into one matrix or vector, which can be useful for solving systems of linear equations or performing other operations on multiple variables. The operation is often performed by multiplying each row of one matrix with the corresponding column of another matrix, resulting in a new matrix that represents the solution to the system of linear equations. For example, consider two matrices A and B: ``` A = [1 2;
