发帖数: 119 | 1 俺数学比较差，想请教版上高手这个问题有没有general的solution或者只在特殊情况
下可解：就是一些非线性不等式（比如一些variables的平方和小于一个常数）定义了
一个subspace，然后以一个matrix对这个subspace作线性变换。问题是： 能否
explicitly将线形变换后的subspace表达出来？非常感谢。 | h********0
发帖数: 12056 | 2 it seems the subset you described is not a subspace
since the subset is obtained from a set of nonlinear constraints. | e****z
发帖数: 119 | 3 Oh, yes, they may not define a subspace... sorry I have forgot a lot of
basic mathematical concepts... So can I explicitly formulate these
constraints after the transformation? Thanks a lot.
