The problem is that you are trying to create the inverse of a (nearly) singular matrix:
[0,0;0,1]^(-1)
In any case, solving for C using the matrix inverse is not recommended, the more efficient and more accurate method is to use mldivide, exactly as the inv documentation explains:
SOL.C = SOL.M\SOL.R
Of course that will not get rid of your singular matrix, so you will still need to fix that.
