Per trovare $F$ prendiamo $\mathcal{\hat{O}}_{n+1}$ e ne togliamo la prima riga:
\[ \mathcal{\hat{O}}^{n \uparrow} = \begin{bmatrix} HF \\ \vdots \\ HF^{n-1} \\ HF^n \end{bmatrix} \]
A questo punto è facile constatare che $\mathcal{\hat{O}}^{n \uparrow} = \mathcal{\hat{O}}^n \, F$ ed, essendo $\mathcal{\hat{O}}^n$ invertibile, posso scrivere:
\[ F = [\mathcal{\hat{O}}^n]^{-1} \mathcal{\hat{O}}^{n \uparrow}\]
Risolvendo il sistema trovo $F$.\end{document}

14 Settembre 2013 alle 10:44 in risposta a: Ubuntu + TeXLive 13 + TeXworks problemi di compilazione #88811::
Bene, avevo notato anch’io ma non sapevo come procedere.
Allora rimosso TeXworks tutti i pacchetti di texlive risultano rimossi con lui (così pare dal gestore pacchetti).
Ora vorrei procedere con “installa TeX works dal suo sito come pacchetto indipendente” maaa
arrivo qui https://launchpad.net/~texworks/+archive/stable e poi?
(ho processore Intel, Ubuntu 12.04 e OS a 64-bit se può servire)
::I had the same problem, seems that the problem is related to the environmental variables in Windows 8. I changed the variable “PATHEXT” (it holds the sequence that Windows looks for executables in) from “.COM;.EXE;.BAT;….” to “.EXE;.BAT;.COM”…., this fixed the problem for me. Environmental variables are found under
`Controlpanel>System and security>System>Change settings>Advanced>Environmental variables`Non ho provato perché ora (dopo qualche intoppo) ho completato l’installazione di MiKTeX (e sembra funzionare) ma effettivamente ho PATHEXT: .COM;.EXE;.BAT;
Riporto qui la soluzione nel caso possa servire.
Mi consigliate di rimanere su MiKTeX o installare TeXLive?Hai scaricato il file install-tl.zip da questa pagina? Hai provato a riscaricarlo?
L’ho scaricato e riscaricato da http://ctan.mirror.garr.it/mirrors/CTAN/systems/texlive/tlnet/
