在MATLAB中解决二次方程的最大化问题

Question

How do I solve a quadratic Maximization problem in MATLAB? It seems MATLAB only supports minimization problems, so is there a mathematical concept I can use?

Answer 1

只需在使用最小化函数之前和之后乘以（-1）

Answer 2

Using quadprog function in MATLAB.

This function solves Quadratic Programming problems in MATLAB.

Of course if you want the maxima instead of the minima, you can multiply the cost function by -1.

Good Luck.

Answer 3

The above answer @Drazick seems not right.

quadprog() in matlab requires H to be positive definite. If we simply multiply (-1), - H is a negative definite matrix, which violates the requirement.

Another optimization function called fmincon( ) may help.
