SDEXE Execute pipeline on data using the perClass runtime under Matlab

   OUT=SDEXE(P,DATA)
   [OUT,T]=SDEXE(P,DATA)

 INPUT
    P      Trained pipeline
    DATA   SDDATA object or data matrix (double)

 OUTPUT
    OUT    Execution output
    T      Time of execution

 DESCRIPTION
 SDEXE implements execution of the recognition pipelines via perClass
 runtime under Matlab.  For SDDATA objects, SDEXE returns SDDATA if the
 pipeline P returns soft outputs or SDLAB if it returns decisions.  For
 DATA matrices, SDEXE returns matrix with soft outputs or decision vector
 with indices to the pipeline list (P.list).
