Find a matrix of oblique projector












0












$begingroup$


How I should find this oblique projector matrix in the following task? Information at Wikipedia seems to be a little bit complicated and I haven`t found any practical examples for oblique projections.



Task:



Find a matrix of oblique projector in $R^3$ onto the subspace $U =ls{(1,0,1)^T}$ parallel to the subspace $W = ls{(1,1,0)^T, (0,1,1)^T}$.

          HINTS: “onto the subspace $U$” means that the projector is the identity map on $U$, while “parallel to the subspace $W$” means that $W$ is the kernel of the projector. Construct a simple matrix that has the requisite rank and apply a change of basis to it.
