so question 2 years old: querying embedded objects in mongoid/rails 3 ("lower than", min operators , sorting) and way recommends query nested objects less or greater than: current_user.trips.where('start.time' => {'$gte' => time.now}).count simply doesn't work, returns 0 numerous queries have wrong. i've tried current_user.trips.where(:'start.time'.gte => time.now}).count which 0. none of these throw error. what correct syntax querying nested elements nowadays? seems fair bit of confusion on this. it works expect in environment. (mongoid 3.1.3) class user include mongoid::document embeds_many :trips end class trip include mongoid::document embeds_one :start embedded_in :user end class start include mongoid::document field :time, type: datetime embedded_in :trip end user.create({ trips: [ trip.new({ start: start.new({ time: 5.days.ago }) }), trip.new({ start: start.new({ time: 2.days.f...

the question: write matlab program that i) generates n<=20 random numbers in interval [a,b], n, a, b entered via keyboard my attempt: a = input ('a=') b = input ('b=') n = input ('n=') n = (1:n) r = rand([a,b],[1,n]) end doesn't seem work. following error messages appear "??? subscript indices must either real positive integers or logicals." what doing wrong? ii) write numbers vector/array x no idea how this? matter of putting r = x? iii) write numbers divisible k screen, k entered via keyboard. my attempt: k = input ('k=') t = mod(x,k); x = i:n if mod(x,k) == 0 disp t end end am anywhere near correct? [i've never used stack-overflow before- having trouble formatting things appropriately] sorry get n random numbers in range [a, b]: a = input('a='); b = input('b='); n = input('n='); % floating point: r1 = + (b-a)*rand(1, n); % integers: r2 = round(...
