Question about a matrix of vector element ratios

Click For Summary
SUMMARY

The discussion centers on deriving a vector from a square matrix A, where each element a_{i,j} is defined as the ratio of vector elements v_i and v_j. The key insight is that scaling the vector does not affect the resulting matrix, indicating a level of flexibility in vector selection. Additionally, the summation of matrix elements over the index i is suggested as a potential method for further analysis or approximation of the vector.

if I have square matrix A whose decimal elements a_{i,j} = \frac{v_i}{v_j} how do I find (or approximate) the vector that would produce the matrix elements. what's a good way to do that?

i guess you can scale the vector however you want and it'll still produce the same matrix..

thanks.

Consider what summing the matrix elements over i produces.
