How to create a sequence of numbers on the GPU

I want to do the follow in a new GPU Array, efficiently:
myarray = 1:100000
gpuArray(1:100000) works of course, but if I'm not wrong it's creating the large array in main memory then moving the whole thing to the GPU. I would expect that I can create the sequence of numbers on the GPU directly more efficiently, as I can do with many random numbers.

The direct equivalent is to use gpuArray.colon, like so:
myarray = gpuArray.colon(1,100000);
