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. WebMATLAB always uses the LAPACK libraries to calculate eigenvectors which works on double precision, floating point numbers - MATLAB's default data type. Mathematica's method depends on its input type. For example, when you do TestMatrix = { {1, 2, 3}, {3, 1, 2}, {2, 3, 1}} Eigenvectors [TestMatrix] WebI get the eigenvalues a1=7, a2= Sqrt [2], a3= -Sqrt [2] with Mathematica just as the book example. How can I use Mathematica to acquire the normalized eigenvectors (column matrices), as in the book example a1> = (1, 0, 0), a2> = (0, 1/Sqrt [2 (2-Sqrt [2])], I (Sqrt [2]-1)/Sqrt [2 (2-Sqrt [2])] and ilary anoressica
