Basic Examples (1)
m is a matrix with two real and two complex eigenvalues:
| In[1]:= |
| Out[1]= |  |
With RealBlockDiagonalForm->False, the result is complex upper triangular:
| In[2]:= |
| In[3]:= |
Out[3]//MatrixForm= | |
 | |
With RealBlockDiagonalForm->True, there are real 2×2 blocks along the diagonal:
| In[4]:= |
| In[5]:= |
Out[5]//MatrixForm= | |
