WebOct 29, 2013 · 1 The task I have is pretty simple but I can not solve it in mathematica. Given a list myList = {1, 3, 4} I would like to get the position of entries smaller than a number - say 2 in the example above. Attempts such as Position [myList, # [ [1]] < 2 &] Position [myList, # < 2 &] which would be similar to the function SELECT don't work. WebFeb 20, 2012 · An Eigensystem command is also included. If you compare with the Eigenvalues and Eigenvectors commands, Eigensystem first returns a vector containing the eigenvalues for the matrix. It then returns the eigenvectors in the same order as their associated eigenvalues.
