Definition
A 'singular matrix' is a square matrix whose determinant is zero. This means it doesn't have an inverse. π« Think of it like a broken machine that can't be undone. Singular matrices cause problems in solving linear equations. They're like a road with no return. π£οΈ Unlike non-singular matrices, they can't be used to uniquely solve systems. Singular matrices crop up in many math and engineering applications. π·
