What is another word for diagonal matrix?
Pronunciation: [da͡ɪˈaɡənə͡l mˈe͡ɪtɹɪks] (IPA) 
A diagonal matrix, also known as a diagonalizable matrix, is a special type of matrix where only the diagonal elements have non-zero values. There are different synonyms for diagonal matrices, depending on their properties and applications. For example, symmetric matrices are a type of diagonal matrix where the diagonal elements are equal to each other and the off-diagonal elements are mirrored across the diagonal. Positive-definite matrices are another type of diagonal matrix that represents a convex function. Other synonyms for diagonal matrices include block-diagonal matrices, where the diagonal elements consist of smaller diagonal matrices arranged in a block pattern, and orthogonal diagonal matrices, which have an orthonormal set of eigenvectors.
