PROCM

Fixed-cell mapping to execute arbitray Matlab function on objects

Low-level routine

     [OUT1,OUT2, ..] = A*PROCM(COMMAND,PAR1,PAR2,....)
     [OUT1,OUT2, ..] = {A,B}*PROCM(COMMAND,PAR1,PAR2,....)

Input
A	Dataset, datafile, cell array or double
B	Dataset, datafile, cell array or double
COMMAND	String with function name or PRTools nmapping
PAR1,...	Optional parameters for COMMAND

Output
OUT1,	... Cell arrays with results from COMMAND

Description

This routine executes a given COMMAND over a set of objects. These can  be supplied by a dataset, a datafile, a cell array or a double array.  Rows are interpreted as objects. For each object N stored in A the  routine COMMAND is processed by

      [OUT1{N}, ...] = COMMAND(OBJECT_N,PAR1,PAR2,....)

For diadic operations the two inputs should be combined in a cell: {A,B}.  They are processed by

      [OUT1{N}, ...] = COMMAND(OBJECT_A_N,OBJECT_B_N,PAR1,PAR2,....)

This is a low-level routine that feeds the unpacked objects in datafiles  and dataset (doubles) to COMMAND. Use FILTM for a higher level of  processing. Use MAPM to handle entire matrices, datasets or datafiles  instead of processing object by object.
