Problem 2336. Calendar Matrix

Return a calendar matrix for the given values of month and year. Assume that Sunday is the first day of the week. The resulting calendar month will have seven columns and only as many rows (weeks) as needed to display all days of the month. Thus it might have either 4, 5, or 6 rows. Days preceding the first of the month or following the last of the month are given by zeros.

Examples

 >> mo = 1
 >> yr = 2014
 >> momat = makeCalendar(mo,yr)

     0     0     0     1     2     3     4
     5     6     7     8     9    10    11

    19    20    21    22    23    24    25
    26    27    28    29    30    31     0

 >> mo = 2
