求助: 3*3 matrix eigenvalue problem# Computation - 科学计算l*e2005-04-29 07:041 楼我需要遍一个小程序算出3*3 matrix 的eigenvalues and eigenvectors.哪位大侠能提供一个类似的程序啊?多谢了!!
c*z2005-04-29 07:042 楼matlab can do that easily,use the command eig.If you don't have matlab,maybe you can try scilab, which I think is free.【在 l******e 的大作中提到】: 我需要遍一个小程序算出3*3 matrix 的eigenvalues and eigenvectors.: 哪位大侠能提供一个类似的程序啊?: 多谢了!!

l*e2005-04-29 07:044 楼多谢longhei 和 cqxz!!我其实是要不停的调用这个程序来算n多个不同的3×3矩阵。所以还是得自己写程序。不过还是谢谢二位了!还有,我已经搞定了,呵呵.【在 l*****i 的大作中提到】: only 3*3, you can even use your pencil and paper to compute it if you do: n't have matlab
