[Octave-bug-tracker] [bug #53242] tests: 'test subspace.m' fails randomly

[Dan Sebald]

Follow-up Comment #5, bug #53242 (project octave):

Something else I should point out.  Generally, the definition of subspace can
be of different vector size, i.e., different space dimensionality (hence the
word "sub"):

https://en.wikipedia.org/wiki/Angle#Angles_between_subspaces
https://en.wikipedia.org/wiki/Angles_between_flats

If I were to add a dimension to one of the vectors, say,

a(end+1)
subspace(a,b)

I think that the result should be the same.  But the current routine doesn't
allow it:

error: subspace: column dimensions of A and B must match
error: called from
    subspace at line 42 column 5
    test_script3 at line 18 column 5
