Question

RRB Paper · Accepted Answer

A square matrix is called singular if its determinant is zero. A square matrix is singular if and only if it does not have an inverse. If the determinant of a square matrix is non-zero, then it is called non-singular, and it has an inverse. The determinant of a square matrix is a scalar value that is calculated using the elements of the matrix. It provides important information about the properties of the matrix, including whether or not it is invertible. A matrix with a determinant of zero is said to be degenerate, and it has linearly dependent columns (or rows), which means that its columns (or rows) are not linearly independent.
