Determinant of a inverse

WebInverse of a matrix is an important operation in the case of a square matrix. It is applicable only for a square matrix. To calculate the inverse, one has to find out the determinant and adjoint of that given matrix. Adjoint is given by the transpose of cofactor of the particular matrix. The formula to find out the inverse of a matrix is given as, WebFind the determinant of A by using Gaussian elimination (refer to the matrix page if necessary) to convert A into either an upper or lower triangular matrix.
