Yeah, I thought he asked for a general solution. Or is that a homework/coursework question too? Anyway, I like the hints idea :).

Thanks Peeter for your reply. So in my example, the non-orthonormal basis would be W and V would be its reciprocal frame? By multiplying V*AW, I get the coordinates in the non-orthonormal basis W (in cols(W) directions) by dotting V*A ?

I cannot visualise an oblique projection. I understood the orthogonal one: The orthogonal projection is P=U\cdotU*, where U is an orthonormal matrix (basis of a subspace) : U*\cdotU=I . Now the projection of matrix A on U vectors is: PA=U*\cdotA\cdotU . For the orthogonal projection, for a...

Well, first you have get a proper transfer function. You do that by dividing the numerator to the denominator to find the direct part of the sistem (D) : y(s) = D*u(s). So in your case that would be 1/2. Now you have a proper transfer function (a first degree polynomial on a second degree...
