Arduino IO with AccelStepper

Hi, I am pretty new to all of this. The plan is to control two stepper motors with Accel Stepper via Matlab. So I was wondering-

1st) Is it possible to use an Arduino library like Accel Stepper via Matlab (using the Arduino IO package) - I have researched a bit but have not found anything on the internet so far dealing with this particular combination. In case this is possible is there anything special I have to take care of when installing Arduino IO? For example, I am not sure if I should upload adio.pde adioe.pde or adioes.pde for my needs.

2nd) I got some idea how the code would have to look like in the Arduino program, but now that I have to use Matlab- would I have to change it into Matlab "speak"?

Many thanks in advance for any advice!
