[julia-users] how use find ?

[paul analyst]

I need all indexes where a[:] >5 

julia> a=rand(10)*10
10-element Array{Float64,1}:
 4.84005
 8.29994
 8.8531
 3.42319
 2.60318
 7.25313
 0.816263
 4.44463
 6.71836
 4.65337

julia> a.>5
10-element BitArray{1}:
 false
  true
  true
 false
 false
  true
 false
 false
  true
 false

julia> find(a.>5,a)
ERROR: no method find(BitArray{1}, Array{Float64,1})

julia> find([a.>5],a)
ERROR: no method find(BitArray{1}, Array{Float64,1})
