Making a matrix in a for loop -


i working mathematica , got stuck on technicalities.

rvec[r_] := unitvector[length[r], randominteger[{1, length[r]}]] fvec[r_] := r - rvec[r] + rvec[r] vec[r_] := module[{s = fvec[r]}, if[count[s, -1] > 0, r, s]] loop[r_, n_] := for[i = 1; l = r, < n + 1, i++, l = vec[l]; print[l]]

the idea have loop going randomly subtract 1 number 1 entry in set , add in next iteration, catch no entry can drop below zero. output set of outcomes put beneath each other.

having done know how put entire output in form of 1 matrix:

instead of having output that, have in matrix form, in having set of outputs placed in larger set containing sets elements. me, able manipulate , work entire output.

if need make matrix consequently adding vector vector, can this:

vector = {1, 2, 3, 4, 5}; matrix = {};   (* initialize matrix *) do[matrix = append[matrix, vector], 5];   (* construct matrix adding line line*) matrixform[matrix]   (* print matrix *)

please tell me if didn't understanf youy problem properly.

Add a dynamic header in angular 2 http provider -

i have http interceptor built via tutorial https://scotch.io/@kashyapmukkamala/using-http-interceptor-with-angular2 the problem need have dynamic header changes automatically once changes 'mode' in app. service able tell interceptor change header, or have interceptor pull header (which string)from service each request. able throwing away patch method, call http.patch('new header string') set header string. call in service controls 'mode' setting. wondering if there way interceptor pull recent value service each request or if can add method http provider via interceptor? i've tried call service in interceptor each request returns undefined. because creating new instance of service or copying value before service fired , loaded/changed data. i don't want pass header string every http provider call because defeats purpose of having interceptor, id able set once changes or have provider fetch service before makes request. tl;dr : need add autom
