CPU usage	Jacket only contains GPU computing functions. To run functions on the CPU, try one of the MathWorks products: http://www.mathworks.com/access/helpdesk/help/techdoc/ref/double.html
More Details	Use the standard MATLAB conversions to return data to the CPU (see below). Examples Usage: A = gdouble(rand(4) + 8); B = (A + 4)/9; C = double(B); bring back to CPU

All subsequent computations on A are performed on the graphics card (GPU).
Actual GPU computation is delayed until the results are requested.
If the currently selected GPU is not double precision capable, this command issues a warning and casts to single precision.
