+% DESCRIPTION: ISPARAM look for a given key in the parameter lists. Exist the key
+%              in the parameter list then is the result 1 otherwise 0.
+%              The output size have the same numer as the numer of the input
+%              plists.
+%
+% CALL:        res = isparam(pl, 'key')
+%              res = isparam(pl1, pl2, 'key')
