I have a problem with a loop that I would like to write in Mathematica. I have a function sigma that changes with i. and I have a function alpha that changes with sigma. Imagining that i goes from 1 to 100, in another system I would write something like: sigma=zeros(100,1); alpha=zeros(100,1); for i=1:100; sigma(i,1)=some function of i; end for i=1:100; alpha(i,1)=some function of sigma(i,1); end and I would get 2 vectors (100,1). Please let me know if you can help me MANY THAnks, isabella
