 Dec 17 accepted Eigenvectors of special matrix with characteristic polynomial Dec 17 comment Eigenvectors of special matrix with characteristic polynomial correct, i had intended to include "monic" and somehow skipped it. Edited question. Dec 17 revised Eigenvectors of special matrix with characteristic polynomial added 6 characters in body Dec 17 asked Eigenvectors of special matrix with characteristic polynomial Dec 17 comment Finding a similarity transform for a matrix that minimizes the (2-norm) condition number and P is just any matrix of eigenvectors of A? (as per en.wikipedia.org/wiki/Diagonalizable_matrix) I guess this is implied by $AV=V\Lambda \rightarrow V^{-1}AV = \Lambda$ en.wikipedia.org/wiki/… Dec 17 comment Finding a similarity transform for a matrix that minimizes the (2-norm) condition number interesting... are there invertible matrices that are not diagonalizable? Dec 16 revised Finding a similarity transform for a matrix that minimizes the (2-norm) condition number found counterexample Dec 16 asked Finding a similarity transform for a matrix that minimizes the (2-norm) condition number Dec 15 comment Can some clearly explain about lim sup and lim inf? dumb question: are inf and sup just fancy math names for min and max?

(I think c is the newest, not positive though) Nov 9 comment What is Cauchy Schwarz in 8th grade terms? Vectors are awesome! If you haven't learned them yet, there's a lot to look forward to. (I'm an EE, not a mathematician, use vectors all the time at work.) Nov 9 revised Explanation of Chandrupatla's algorithm for root finding? added 94 characters in body
