list->sequence



Dear Maxima-Mailing List

I have a very basic problem:

Is there a command to convert
a list of lists into a matrix?

More generally, is there a way
to convert a list into a sequence,
i.e.:
[a,b,c] -> a,b,c

Or having a list [a_1, ... a_n],
how can I apply this "list" to
a function that takes as input
an arbitrary length "sequence" a_1,...,a_n , 
as for instance the function "matrix"?

  Thanks again

   Fabrizio
