sol <- solve.QP(Dmat, dvec, Amat, bvec, meq=0) 参数Dmat表示海赛矩阵 参数dvet表示一阶向量,和Dmat的维数要相对应。 参数Amat表示约束矩阵,默认的约束都是是>=。 参数bvet表示右边值,由向量,和Amat的维数要相对应。 参数meq表示从哪一行开始Amat矩阵中的约束是需要被当作等式约束的。 结论 让我们检查...
`quadprog` 是一个用于解决二次规划(Quadratic Programming,简称 QP)问题的函数或工具。二次规划是数学优化的一种,它涉及在一个线性等式和不等式约束下,最小化一个二次目标...
Quadprogpp 是由Luca Di Gaspero所写的 c++ QP问题求解器, 其功能与Matlab中的二次规划solver一致。 在QP问题中,其标准形式为: $$ \begin{aligned} \underset{x}{min} &f = \frac{1}{2}x^TGx + g_0^Tx \ s.t:& \ &CE^Tx + ce_0 = 0 \ &CI^Tx + ci_0 \geqslant 0 \ \end{ali...

quadprog/quadprog/solve.QP.c Line 259 in if(iact[i]>meq&&((!reverse_step&&rv[i]>0.)||(reverse_step&&rv[i]<0.))) { is unnecessary as it will never be set for inequality constraints. Sorry this issue isn't more helpful.
I used to use function qp to solve the quadrature programming problem. Since qp does not exist, I wonder how the input/output arguments of qp correspond to the input/output arguments of quadprog. 댓글 수: 2 Matt J2018년 9월 20일 ...
qp二次规划函数 目标函数为二次函数二约束函数为线性 假如你的问题确实是二次规划函数的话，那详细参考帮助，This example shows how to solve a simple quadratic programming problem. It finds values of x that minimize f(x)=1/2*x1^2+x2^2-x1*x2-2*x1-6*x2 目标函数 subject to...
EDIT: Forgot to also ask: if J = (1/2)*x'*H*x + f'*x is the objective function to be minimised, the MPC objective form has to be transformed into this form, for QP problems. This only allows you to minimise a single variable, instead of x,u, du etc... with the appropr...
