Problem inverting complex matrix
Consider this complex matrix:
M1 = \begin{bmatrix} 0.0005 & 0 & 0 & -0.0005 & 0 & 0 & 0 & 1 \\ 0 & 9.69696969697E-4+0.00125i & 0 & -0.00125i & -6.66666666667E-4 & -3.0303030303E-4 & 0 & 0 \\ 0 & 0 & 3.57142857143E-4-0.0025i & 0 & 0.0025i & 0 & -3.57142857143E-4 & 0 \\ -0.0005 & -0.00125i & 0 & 0.0005+0.00125i & 0 & 0 & 0 & 0 \\ 0 & -6.66666666667E-4 & 0.0025i & 0 & 6.66666666667E-4-0.0025i & 0 & 0 & 0 \\ 0 & -3.0303030303E-4 & 0 & 0 & 0 & 3.0303030303E-4-1.66666666667E-3i & 0 & 0 \\ 0 & 0 & -3.57142857143E-4 & 0 & 0 & 0 & 3.57142857143E-4+0.005i & 0 \\ 1 & 0 & 0 & 0 & 0 & 0 & 0 & 0 \\ \end{bmatrix} Inverting with the HP-Prime using 1/M1 works: Inverting it using inv(M1) fails. Is this a bug or there is something I failed to consider? If you want to try, M1.hpmat is included in this zip file: M1.zip (Size: 289 bytes / Downloads: 9) |
