Dear Group: I want to write a function that accepts a n-vector and an n x m matrix. It should return a list of positions in the matrix where mat[[i,j]] > vec[[i]]. For example, In[287]:= vec=Table[Random[],{2}] Out[287]= {0.482259,0.314393} In[288]:= mat=Table[Table[Random[],{4}],{2}] Out[288]= {{0.183706,0.758693,0.462242,0.170041},{0.457054,0.349658,0.805455,0.127763}} I would like myFunc[] to return {{2},{1,2,3}}. How could I write this as a pure function? Ideally I would like to be able to Map or Apply my function to the list {mat, vec} and get my result. Something like Position[#1,_?(#>#2&)]&@@{mat,vec} is doomed to fail because the PatternTest required in Position[] messes up the slotting of the other arguments. Ideas? How do you nest pure functions? -- Curt Fischer
