When does a matrix have an inverse?

A matrix has an inverse if and only if it is a square matrix with the same number of rows and columns and its determinant is non-zero. Such a matrix is called non-singular or invertible.

Can every square matrix be inverted?

No, only non-singular (invertible) square matrices can be inverted. A matrix is considered non-singular if its determinant is non-zero. Conversely, if the determinant is zero, the matrix is singular and does not have an inverse

What is the adjugate (adjoint) of a matrix?

The adjugate (or adjoint) of a matrix is the transpose of the cofactor matrix. It is used in the process of finding the inverse of a matrix.
