  PLASMA_cgetri - Computes the inverse of a matrix using the LU factorization computed by PLASMA_cgetrf. This method inverts U and then computes inv(A) by solving the system inv(A)*L = inv(U) for inv(A). Parameters
  [in] | N | The order of the matrix A. N >= 0.
  [in,out] | A | On entry, the triangular factor L or U from the factorization A = P*L*U as computed by PLASMA_cgetrf. On exit, if return value = 0, the inverse of the original matrix A.
  [in] | LDA | The leading dimension of the array A. LDA >= max(1,N).
  [in] | IPIV | The pivot indices that define the permutations as returned by PLASMA_cgetrf.
  Returns Return values
  PLASMA_SUCCESS | successful exit
  <0 | if -i, the i-th argument had an illegal value
  >0 | if i, the (i,i) element of the factor U is exactly zero; The matrix is singular and its inverse could not be computed.
