Not every linear transformation from [img=22x19]1803b6a8affc14b.png[/img]to [img=25x19]1803b6a8b9210ff.png[/img]is a matrix transformation.
举一反三
- The columns of the standard matrix for a linear transformation from [img=22x19]1803b6a8c19a71a.png[/img]to [img=25x19]1803b6a8c9f3863.png[/img] are the images of the columns of the [img=44x19]1803b6a8d3fc1b1.png[/img] indentity matrix.
- Every matrix transformation is a linear transformation.
- Every matrix transformation is a linear transformation. A: 正确 B: 错误
- The transformation that takes x to 2x+1 is a linear transformation.
- Let [img=99x19]1803c4e7d6c70bb.png[/img] be a linear transformation. If A is the standard matrix representation of [img=13x19]1803c4e7de70caa.png[/img], then an [img=44x19]1803c4e7e5f3add.png[/img] matrix B will also be a matrix representation of L if and only if B is similar to A.
