求助关于householder和given rotation
<p>谁知道这道题应该怎么解啊?!谢谢帮助!</p><p>Let x 2 Rm and let H be a Householder reflection such that Hx = ±||x||2e1. Let<br/>G1,2, G2,3, ..., Gm−1,m be Givins rotations and let G = G1,2G2,3...Gm−1,m. Suppose<br/>Gx = ±||x||2e1. Must H equal G? You need to give a proof or a counterexample.</p>
