This reverts commit 7541bb52.

This commit was breaking compilation of MEX files: the subdir-objects option
does not deal well with source files that are under a distinct tree.

(cherry picked from commit 80218a1b)

This method can be used to apply the lead and lag methods an arbitrary number of times to a dynSeries object. For instance, if ts is a dynSeries object, and if we define

>> B = dynTimeIndex()-1;
>> F = dynTimeIndex()+1;

B and F can be used as lag and lead operators and the following syntax:

>> us = ts(F^2);

is equivalent to

>> us = ts.lead(2)

or

>> us = ts.lead.lead

Added missing case for set_names in subsref. This commit and the previous one fix the bug in @dynSeries::set_names method reported at http://www.dynare.org/stepan/dynare/tests/report-f4c01a43bc2882e7fd18f3cd82344fff9644088c.log.

Fixed unitary tests. If not specified, the name a variable in a dynSeries object is not '--NaN--' but 'Variable_xx' where x is the number of the variable.

Fixed bug (The argument of inputname must be the input argument number not the input argument itself).

See http://www.dynare.org/stepan/dynare/tests/report-f4c01a43bc2882e7fd18f3cd82344fff9644088c.log

Suppose that ts is a dynSeries object and let

t = dynTimeIndex();

Then

us = ts.lag();  <=>  us = ts(t-1);

us = ts.lag(2);  <=>  us = ts(t-2);

us = ts.lead();  <=>  us = ts(t+1);

Added corresponding unitary test.

Moved the commented first line, used to declare that the routine has unitary tests, after the declaration of the function, otherwise help is not displayed.

Added new interface to dynDate. The constructor accepts a character ('Y', 'A', 'Q', 'M' or 'W') as the second input to specify the frequency instead of an integer (1, 4, 12, or 52). The following expressions are equivalent:

a = dynDate([1945 3],4);
a = dynDate([1945 3],'Q');

Added tests in dynDate constructor (when dynDate is called with two input arguments: time and frequency).

Follwing expressions are equivalent:

a = dynDate('2009');
a = dynDate('2009y');
a = dynDate('2009a');
a = dynaDate(2009);

Bugfix for conditional variance decomposition

Cosmetic fix

sigma_e_is_diagonal was erroneously set to 0 if the covariance matrix was diagonal, but contained a 0 on the main diagonal.

Added argument to shiftS routine so that it can be called recursively to remove more than one element in a one dimensional cell array.

Changed the syntax so that the difference between calling a member or a method is more explicit (dynSeries).

Changed the syntax so that the difference between calling a member or a method is more explicit (dynDates) and added unitary tests.

If a is a dynDate object:

a.format or a.format() are allowed because format is a method.

a.freq is allowed but a.freq() returns an error message because freq (same for time) is a member.
