 January 14, 2000, 14:55 windowsNT #1 jy Guest   Posts: n/a When clicking on the icon of program I sometimes have this message: cannot find program.exe in C:/directory/ windownsNT need this program to run program.exe ??? Has anybody have this problem? I am really clicking ON the program icon (!) I have tryed everything (path, indexing, rename, move, from DOS prompt...) and it is the same...and of course the program is IN the directory...I am clicking on it(?!) I actually happens with 2 or 3 program thanks jy

Check by right clicking on the icon and selecting 'Properties'. The path that it is looking for is listed there.

 February 1, 2000, 10:25 generalized eigenvalues #4 Ciro Caramiello Guest   Posts: n/a Let us suppose that we want to solve this generalized eigenvalue problem: A*z=lambda*B*z where A and B are two (n*n) matrices in particular A is full-rank while B has one or more null (all zeros) rows. I'd like to know more algebraic details on this problems since the generalized spectrum has n-m eigenvalues and, consequently, n-m eigenvectors (to prove this apply directly the definition of characteristic polynomial) where m is the number of zero rows. Moreover I'd like to get more infos about the QZ algorithm which proved to find correctly the n-m eigenvalues but, of course, assigns infinity values to the m "phantom" eigenvalues. What about the corresponding eigenvectors especially when A is quasi rank deficient? Please contact me if you think you could be help to solve this non-classical problem of linear algebra and numerical analysis

 February 16, 2000, 12:46 Re: generalized eigenvalues #5 clifford bradford Guest   Posts: n/a notes and references on the solution to eigenvalue problem can be found in the MATLAB users guide under the EIG function. i suppose you could also try numerical recipes or other numerical linear algebra books for notes and references
