Solving an equation with symbolic matrix

I've tried solving eq1 in the following program.
The right answer is w = -D*lambda*unos
%start
unos=ones(2,1)
ceros=zeros(2,1)
E = symmatrix('E',2)
D=inv(E)
w=symmatrix('w',[2,1])
eq1= w + D*lambda*unos==ceros
solve(eq1,w)
%end
The right answer is w = -D*lambda*unos
But instead, I get the following message:
Check for incorrect argument data type or missing argument in call to function 'solve'.
Please help
