[julia-users] How can I delete columns of a matrix in-place?

[Diego Javier Zea]

Is there some function for deleting columns in-place? I want to do 
something like the next, but changing the matrix in-place.

julia> mat = [ 1 2 3
       4 5 6 ]
2x3 Array{Int64,2}:
 1  2  3
 4  5  6

julia> mat[:, [true, false, true]]
2x2 Array{Int64,2}:
 1  3
 4  6


Thanks in advance!
