ok, I tried nullspace(A) with my matrix:
(%o11) matrix([-2,-5,8,0,-17],[1,3,-5,1,5],[3,11,-19,7,1],[1,7,-13,5,-3]
(%i12) nullspace(%);
(%o12) span(matrix([0],[1],[1/5],[-1],[-1/5]),matrix([1],[0],[-3/5],[-2]
[-2/5]))
maxima find out a different solution of my book! this is the solution of my
book:
[-1] [-1]
[2] [-3]
{ [1], [0] }
[0] [5]
[0] [1]
By the way I need the reduced form too and not only the null space...
