It is probably not possible at this time. Although you can useMATLAB Coder to generate code that you can compile on iPAD, there are a lot of parts of MATLAB that you cannot generate code for. The third party toolbox you are interested in was not designed for compiling, and if I understand correctly relies a lot on third-party drivers in order to achieve the I/O rates that it does; you would have to find similar drivers for iPAD for the portions you need.
If your MathWorks Account is associated to a license that has Signal Processing Toolbox, you should be able to use it on your iPad. Note that the limitations mentioned in the 'System Requirements' section of this page would still apply: https://www.mathworks.com/products/matlab-mobile.html
