Ariel,
you can use VectorSpace, as in the example below. The documentation for
GAP4 can be found at
http://www.gap-system.org/Doc/doc.html
Regards,
Sven.
gap> V1 := VectorSpace(Rationals, [[1,0],[0,1]]);
<vector space over Rationals, with 2 generators>
gap> V2 := VectorSpace(Rationals, [[1,0],[1,1]]);
<vector space over Rationals, with 2 generators>
gap> V1 = V2;
true

Hi,
Im using GAP GAP4, 4.4.7, i need to use RowSpace but i dotn know how to
use it and:
gap> ?RowSpace
Help: no matching entry found
Help: 'RowSpace' is currently undocumented.
For details, try ?Undocumented Variables
so i found this: http://schmidt.nuigalway.ie/gap/CHAP033.htm
but even some of those examples give me errors.
All i need to do is to compare two matrices, by comparing what they
generate.
Is there a GAP4 documentation somewhere? Google only gives GAP v3 docs
gap> RowSpace(Rationals, MatTom(TableOfMarks(SmallGroup(16,3))));
Error, usage: FullRowModule( <R>, <n> ) for ring <R> called from
<function>( <arguments> ) called from read-eval-loop
Entering break read-eval-print loop ...
you can 'quit;' to quit to outer loop, or
you can 'return;' to continue
Thanks in advance!
