# Thread: SVD and eigenvalues

1. ## SVD and eigenvalues

This is the question i asked before. I need some help here as i am very poor in computing. Some hints or help will be really appreciated.

Question: Let A be the $m \times m$ upper-triangular matrix with 0.1 on the main diagonal and 1 everywhere above the the diagonal. Write a programe to compute the smallest singular value of A in two ways. By calling a standard SVD software, and by forming A*A and computing the square root of its smallest eigenvalue. Run the program for $1 \leq m \leq 30$ and plot the result as two curves on a log scale. Do the result confirm to our general discussion of these algorithms?

Thanks
