Hello Smath community, I have a problem that I can't fix. In this worksheet I want to create a matrix "R" that contains the roots of a polynomial for different values of the parameter "w". I created a for loop that should be able to do this but I dont know how to index inside the for loop for different columns of "R" (Each column should be the roots for each value of the parameter).eigen.sm (10 KiB) downloaded 63 time(s).
