Details:

In the example below M.values(keySet) fails, while values(M, keySet) succeeds,
in all of octave 5.2, 6.1, 7.0. In matlab both forms work.

Apparently in octave first v=M.values is evaluated, and then v(keySet) fails.


months = {'Jan', 'Feb', 'Mar', 'Apr'};
Tamb = [10, 11, 15, 18];
M = containers.Map(months, Tamb);
keySet = {'Jan', 'Feb'};
valueSet = values(M, keySet)
valueSet = M.values(keySet)


output:


valueSet =
{
  [1,1] =  10
  [1,2] =  11
}

error: index (<cell>): subscripts must be either integers 1 to (2^31)-1 or
logicals
error: called from
    subsref at line 399 column 14
    xx at line 6 column 10
