Details:

randsvd, pei, kms, hanowa, gearmat functions in gallery.m raise error when
called. These were the outputs when called and the corresponding solutions.


gallery('randsvd',4)
error: 'qmult' undefined near line 2271 column 9
error: called from
    gallery>randsvd at line 2271 column 7
    gallery at line 486 column 45


Which was solved by adding the GPL'd file qmult.m, note that randsvd is part
of N. J. Higham's Test Matrix Toolbox (3.0).


>> gallery('pei',4)
error: 'w' undefined near line 2018 column 24
error: called from
    gallery>pei at line 2018 column 3
    gallery at line 475 column 44
error: evaluating argument list element number 1
error: called from
    gallery>pei at line 2018 column 3
    gallery at line 475 column 44



>> gallery('kms',3)
error: 'mu' undefined near line 1608 column 23
error: called from
    gallery>kms at line 1608 column 3
    gallery at line 461 column 44
error: evaluating argument list element number 1
error: called from
    gallery>kms at line 1608 column 3
    gallery at line 461 column 4



>> gallery('hanowa',4)
error: 'lambda' undefined near line 1274 column 24
error: called from
    gallery>hanowa at line 1274 column 3
    gallery at line 453 column 44
error: evaluating argument list element number 1
error: called from
    gallery>hanowa at line 1274 column 3
    gallery at line 453 column 44
-verbatim+

The last one, 'gearmat', was trickier. Boolean operations needed rewiring:


>> gallery ('gearmat',3)
error: gallery: I must be a nonzero scalar, and abs (I) <= N for gearmat
matrix.
error: called from
    gallery>gearmat at line 1219 column 5
    gallery at line 450 column 44


A .diff is attached. I have also written a test (with the aid of block editing
in vim) for each function in the gallery to check that the rest are OK.
