Is there any explanation for quadratic programming?

I don't quite understand the logging of QP.

1. What's the meaning of QLMatrix in the log?
2. I have no coefficient less than 1, why there's a 7e-2 in QLMatrix?

  The QLMatrix refers to the linear coefficients of you quadratic constraints. As an example, for

  \[x^2 + x\cdot y + 2\cdot x - 10\cdot y \leq 0\]

  the QLMatrix range would be [2e+00, 1e+01].

  I have no coefficient less than 1, why there's a 7e-2 in QLMatrix?

  You could write your model to a file and analyze the coefficients.
