→ ggLer:1的平移T(x)=x+a a不為零時就不是linear了 03/18 21:31
→ ggLer:least square solution A是不是獨立都可以求吧~~@@ 03/18 21:33
→ nana0130:喔，那這樣，不管怎樣ax=b的least-square 都能有解啊 03/18 23:22
推 epyon:3.應該是b向量不屬於col(A)時 才需要用Les 來近似 03/19 14:01
you must have detailed explanation.
1. which of rotation, translation, scaling, and perpective projection
are linear transformation?
我只知道translation 不是,但我不懂原因及如何解釋
2. what formulas will make the non-linear transforations into
matrix transformations?
不懂
3.When will you find the least-squares solution for Ax=b?
我認為是 A 有行獨立時候
請問對嗎 ?
感謝大家
