MapleV: substitution in linalg problem
Posted:

I can't figure out how to substitute values for the tparameters in the solution of the following problem. Many thanks in advance for any hints. Meinrad
> with(linalg): # Let's say we have the following (singular) matrix: > A:=matrix(2,2,[4,3,8,6]);
[4 3] A := [ ] [ 8 6]
# I solve for solutions of the homogenous system A*x=0: > x:=linsolve(A,vector(2,[0,0]),'r',t);
x := [t[1], 4/3 t[1]]
# I simply want to substitute certain integer values into this solution # vector. How do I achieve this? For example, the following procedure # does not give me what I want: > evalm(subs(t[1]=2,x));
[t[1], 4/3 t[1]]
