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?

u1 = 5;
A = randi([-9 9], u1, 1); %u1 x 1
x=sym('x',[1 u1])
e=ones(u1,1)
eqn=[x*A==0 ,x*e==1]
solx=solve(eqn,x)
subs(x,solx)

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