Description
In linear algebra, an n-by-n square matrix A is called invertible (also nonsingular or nondegenerate) if there exists an n-by-n square matrix B (the inverse matrix of A) such that
AB=BA=I
where I denotes the n-by-n identity matrix and the multiplication used is ordinary matrix multiplication. If this is the case, then the matrix B is uniquely determined by A and is called the inverse of A.
In linear algebra, the determinant is a useful value that can be computed from the elements of a square matrix. The determinant of a matrix A is denoted det(A), detA , or |A|. It can be viewed as the scaling factor of the transformation described by the matrix.
This app allows the user to find the inverse and determinant of a matrix by simply allowing the user to enter the elements of the matrix.
