A question about code details.

[Hanqer]

May I ask what's the meaning about Matrix Q? What the meaning of the shape-line weight corresponds to is in the paper？ Thank you！
Looking forward to your answer, thank you!

The energy equations are defined via one quad, and the global optimazation is based on the mesh (all quads), so it is a weighted least square problem, the Q is constructed as the weight matrix. Analysis on the dimensions of the matrices would make it more clearly.
