What is the difference between a matrix and a vector?

A matrix is invertible if its determinant is non-zero. If the determinant is zero, the matrix is not invertible.

A matrix is a rectangular array of numbers, while a vector is a one-dimensional array of numbers. In linear algebra, matrices are used to represent systems of equations, while vectors are used to represent points in space.

Step 2: Calculate the Cofactor Matrix

The cofactor matrix is then transposed to obtain the adjugate matrix.

Common Misconceptions

The inverse of the matrix is calculated by dividing the adjugate matrix by the determinant of the original matrix.
