Pregunta: 15. Si M=⎣⎡26−6−14−2033−8−19−2023−1−16−2030−133−14⎦⎤ Factorize M=P−1DP, donde D es una matriz diagonal a bloques ( ver ejemplo 5.6.6)

To factorize the given matrix $\begin{array}{c}\mathrm{M}=\left[\begin{array}{cccc}26& 33& 23& 30\\ -6& -8& -1& -13\\ -14& -19& -16& 3\\ -20& -20& -20& -14\end{array}\right]\end{array}$ into the form $\mathrm{M}={\mathrm{P}}^{-1}\mathrm{D}\mathrm{P}$, where $\mathrm{D}$ is a block diagonal matrix, we need to find th...
