I hvae to solve the simultaneous matrix equations
X*A=0 and X*e=1 where X is a row vector of finite dimension 1Xu and e =ones(u1,1)
I tried the following How can I Solve simultaneous matrix equation X*A=0 and X*e=1 where X a row vector ,e coloumn vector with all entries one.? i have tried
x=sym('x',[1 u1])
e=ones(u1,1)
eqn=[x*A==0 ,x*e==1]
solx=solve(eqn,x)
but the answer i am getting is a structure but i need it as a matrix. can any one help me?

Ran in:
u1 = 5;
A = randi([-9 9], u1, 1); %u1 x 1
x=sym('x',[1 u1])
x = 
(x1x2x3x4x5)
e=ones(u1,1)
e = 5×1
1 1 1 1 1

eqn=[x*A==0 ,x*e==1]
eqn = 
(6 x2−5 x1−x3−3 x4+8 x5=0x1+x2+x3+x4+x5=1)
solx=solve(eqn,x)
solx = struct with fields:
x1: [1×1 sym] x2: [1×1 sym] x3: [1×1 sym] x4: [1×1 sym] x5: [1×1 sym]
subs(x,solx)

Sorry, format is a bit messed up. The output vector has two non-zero entries and the rest are all zero.
