标题[问题]想问关於"用(intel fortran)IMSL解出eigenvetor"的问题쌊时间: Tue Nov 13 19:50:00 2007
各位大大:
我组完矩阵後用(intel fortran)IMSL解eigenvalue & eigenvector
=>问题(1):如何让解出来的eigenvetor是还没正规化的
(也就是Euclidean length不等於"1")
<以下是IMSL User's Guide里的内容>
EVEC — Matrix of order N containing the eigenvectors. (Output)
The J-th eigenvector, corresponding to EVAL(J), is stored in the
J-th column. Each vector is normalized to have Euclidean length
equal to the value one.
=>问题(2):IMSL是如何将eigenvetor正规化,是直接除以它的长度吗?
=>问题(3):想请问为何都会将eigenvetor正规化(Euclidean length等於"1")
====不好意思,第一次来此问问题,如有冒犯之处请见谅&提醒,谢谢!!====
