1 % COMBINE multiple parameter lists (plist objects) into a single plist.

4 % DESCRIPTION: COMBINE multiple parameter lists (plist objects) into a single
5 % plist. Duplicate parameters are given priority in the order
6 % in which they appear in the input.
7 %
8 % CALL: pl = combine(p1, p2, p3);
9 % pl = combine(p1, [p2 p3], p4)
10 %
11 % EXAMPLES: >> pl1 = plist('A', 1);
12 % >> pl2 = plist('A', 3);
13 % >> plo = plist(pl1, pl2)
14 %
15 % Then plo will contain a parameter 'A' with value 1.
