In mathematics, a compound matrix is a type of matrix that is derived from another matrix, specifically an \\( n \\times n \\) matrix, to represent all possible combinations of its elements. The term is often used in the context of determinants. A compound matrix typically yields a matrix whose entries consist of the determinants of all possible \\( k \\times k \\) submatrices of the original \\( n \\times n \\) matrix.
