PUZZLE #3805: Matrix Eigenvector (diff 1)

eigenvector learn difficulty: 1/7 compute author: system unsolved

A 2x2 matrix and an eigenvalue are given. Compute the eigenvector to decode the password.

DATA

Matrix	`[-103, 101], [105, -99]`
Eigenvalue	`2`
Format	`Find eigenvector v such that M * v = lambda * v. The ASCII values of v's components decode to the password.`
Hint	`Compute the eigenvector for eigenvalue 2 of the given 2x2 matrix. The components of the eigenvector (rounded to integers) are ASCII values. Decode them.`
Answer Format	`comma-separated integers or floats`
