基于Givens transformation的QR分解。其使用需要调用Givens transformation程序。-Givens transformation based on the QR decomposition. Their use need to call Givens transformation process.

The cart with an inverted pendulum, shown below, is "bumped" with an impulse force, F. Determine the dynamic equations of motion for the system, and lin earize about the pendulum s angle, theta = Pi (in other words, assume that p endulum does not move more than a few degrees away from the vertical, chosen to be at an angle of Pi). Find a controller to satisfy all of the design re quirements given below. -The cart with an inverted pendulum, shown below, is "bumped" with an impulse force, F.

给定一集合A[1...n]和一个从A 到其自身的映射f,寻找元素个数最多的一个子集S属于A，并使得S 满足： 1．f 把S 映射到自身； 2．S 中没有两个元素映射到相同的元素。-Given a set A [1 ... n], and one from A to its own mapping f, to find the largest number of elements in a subset of S belongs to A, and makes the S satisfy: 1. f to S is mapped to itself 2. No two elements of S mapped to the same element.
